Illustrator CC is having wonderful tools for digital painting such as Paintbrush ,BlobBrush,Eraser tool.The combination gives you desired result.

Brushes let you stylize the appearance of paths. You can apply brush strokes to existing paths, or you can use the Paintbrush tool to draw a path and apply a brush stroke simultaneously.

Difference between Paintbrush and BlobBrush tool-

The blob brush draws stokes that are immediately expanded into shapes.

The brush tool draws paths that have a brush stroke applied. So you can easily change the path and you can change all brush options (including the option to apply a completely different brush).

You can easily just expand the brush stroke. Select all the paths that you have drawn with the brush tool and use Object > Expand appearance. Depending on the other blob brush settings you might need to also use pathfinder functions in order to combine all the shapes.

Paintbrush tool draws paths and apply brush strokes simultaneously 

  • Select a brush in a brush library or the Brushes panel.
  • Select the Paintbrush tool .
  • Position the pointer where you want the brush stroke to begin, and drag to draw a path. A dotted line follows the pointer as you drag.
  • Do one of the following:
    • To draw an open path, release the mouse button when the path is the desired shape.
    • To draw a closed shape, hold down Alt (Windows) or Option (Mac OS) as you drag. The Paintbrush tool displays a small loop . Release the mouse button (but not the Alt or Option key) when you are ready to close the shape.Illustrator sets down anchor points as you draw. The number of anchor points is determined by the length and complexity of the path and by the Paintbrush tolerance settings.Tip: To adjust the shape of a brushed path after you finish drawing it, first select the path. Then position the Paintbrush tool on the path, and drag until the path is the desired shape. You can use the technique to extend a brushed path as well as change the shape of the path between the existing end points.
    • Paintbrush tool options

      Double-click the Paintbrush tool to set the following options:

      Fidelity

      Controls how far you have to move your mouse or stylus before Illustrator adds a new anchor point to the path. For example, a Fidelity value of 2.5 means that tool movements of less than 2.5 pixels aren’t registered. Fidelity can range from 0.5 to 20 pixels; the higher the value, the smoother and less complex the path.

      Smoothness

      Controls the amount of smoothing that Illustrator applies when you use the tool. Smoothness can range from 0% to 100%; the higher the percentage, the smoother the path.

      Fill New Brush Strokes

      Applies a fill to the path. This option is most useful when drawing closed paths.

      Keep Selected

      Determines whether Illustrator keeps the path selected after you draw it.

      Edit Selected Paths

      Determines whether you can change an existing path with the Paintbrush tool.

      Within: _ pixels

      Determines how close your mouse or stylus must be to an existing path to edit the path with the Paintbrush tool. This option is only available when the Edit Selected Paths option is selected.

      BlobBrush tool guidelines

      When using the Blob Brush tool, keep the following guidelines in mind:

      • To merge paths, they must be adjacent in stacking order.
      • The Blob Brush tool creates paths with a fill and no stroke. If you want your Blob Brush paths to merge with existing artwork, make sure that the artwork has the same fill color and no stroke.
      • When drawing paths with the Blob Brush tool, new paths merge with the topmost matching path encountered. If the new path touches more than one matching path within the same group or layer, all of the intersecting paths are merged together.
      • To apply paint attributes (such as effects or transparency) to the Blob Brush tool, select the brush and set the attributes in the Appearances panel before you start drawing.
      • Use the Blob Brush tool to merge paths created by other tools. To do so, make sure that the existing artwork doesn’t have a stroke. Then set up the Blob Brush tool to have the same fill color, and draw a new path that intersects all of the paths that you want to merge together.

      BlobBrush tool options

      Double-click the Blob Brush tool in the Tools panel and set any of the following options:

      Keep Selected

      Specifies that when you draw a merged path, all paths are selected and remain selected as you continue to draw. This option is useful for viewing all paths that are included in the merged path.

      Merge only with Selection

      Specifies that new strokes merge only with the existing selected path. If you select this option, the new stroke is not merged with another intersecting path that is not selected.

      Fidelity

      Controls how far you have to move your mouse or stylus before Illustrator adds a new anchor point to the path. For example, a Fidelity value of 2.5 means that tool movements of less than 2.5 pixels aren’t registered. Fidelity can range from 0.5 to 20 pixels; the higher the value, the smoother and less complex the path.

      Smoothness

      Controls the amount of smoothing that Illustrator applies when you use the tool. Smoothness can range from 0% to 100%; the higher the percentage, the smoother the path.

      Size

      Determines the size of the brush.

      Angle

      Determines the angle of rotation for the brush. Drag the arrowhead in the preview, or enter a value in the Angle text box.

      Roundness

      Determines roundness of the brush. Drag a black dot in the preview away from or toward the center, or enter a value in the Roundness text box. The higher the value, the greater the roundness.

      Eraser tool-

      Illustrator is used to quickly remove areas of artwork as easily as you erase pixels in Photoshop, by stroking with your mouse over any shape or set of shapes.

      By double-clicking the Eraser tool, you can define the diameter, angle, and roundness of your eraser. If you’re using a drawing tablet, you can even set Wacom tablet interaction parameters, such as Pressure and Tilt.

      Double-click the Eraser tool to set various tool options.

      Drag the tool over the area you want to erase but you can control the tool by doing the following:

      • To constrain the Eraser tool to a vertical, horizontal or diagonal line, press Shift-Drag

      • By first creating a marquee around an area, you can erase everything inside the area. Note that new paths are automatically created along the edges of the erasure.

      #paintBrush #blobBrush #eraser tool

      If you want to erase more than a single selected object, use Isolation mode to segregate grouped objects for editing. Remember that in order to enter this mode, you simply double-click a group of items. You can then use the eraser on all objects in that group at one time without disturbing the rest of your design.
