It's rly very well done! ^^ I noticed that you spent a lot of time on it. not just for the size, but also for the dithering! *o*(particulary, I think it's the hardiest shading)
Not really, I have a quick technique for dithering: I make a 2x2 pattern in photoshop, and make a pattern layer with that, then just paint like a brush over the mask, so the final result is dithering, but without pixel-by-pixel placing
I loved the wings *-*
