Needs a pen that does rotation to position the feathers into a nice wing shape. Tilt and pressure affect size.
I like drawing and sculpting feathers, so I made this brush. I feel this does a decent job at sketching the base layer for wings.
The catch is it needs rotation to reach its full potential.

First stroke is with the mouse. It does make a feather, but you want a tablet pen, perferably one that does rotation to do the wings.
