The theme that I chose for my icons is exotic feathers. I chose 12 different birds with very different or colorful plumage. I searched online for the feathers and scetched some of my favorites.
I did a few variations of each one.
This is my vector draft of each of the feathers. I had to hand paint them in illustrator to get the right curves. I started in black and white first before adding color.
Next I added colors that would be found on each of the bird feathers. After some critique I added shadows, changed some of the strokes and color intensity, and tiedied up the shapes to get my final image at the top.
