Oh man, those wings look like so much work! But they're looking good. As for feedback... I like the patterns you did, but it kinda feels like that the halfmoon like shapes on the left wing should be the other way around, like you did on the right wing. Kinda like the feathers layering over each other. I'm not sure if I'm explaining myself right. :')

Anway, it's looking really awesome and I can't wait to see the endresult. :D
