Another Practice Coloring

I can't take full credit for this, since I didn't do the lineart, but I did spend a good portion of my day practicing doing eyes on photoshop and finally came up with one I liked. So here is my shading practice, my eye coloring practice and my 'don't-stay-in-the-lines' practice I think I'm starting to get a hang on this. Sorry if its a bit iffy.

Please tell me how I did :3 Best way for me to learn
