I was bored so I thought why not make this? This is just a simple way I've found to drawing wings that look nice and fluffy. It doesn't take long and only has a few simple steps.

Step I:
For starters decide what way you want the wing, spread, folded, back. Then draw out the basic form.

Step II:
Keeping a loose grip on your pencil, sketch out some bumps and lines in random, do not put much thought into how you draw them.

Step III:
Next you do the same thing as in step two but along the top of the wing and with smaller strokes and bumps.

Step IV:
Then repeat step two again but on the inside of the wing in two rows.

Step V {additional/optional}:
-In lighter, scattered strokes you can add a bit more texture to the wings.
-Add a talon to the wing
-Multiple wings
-Designs
