Nice coloring work. Though i do think the wings could use a bit more detail, especially on the top part. Some more half-circle lines will definitely make it look like the wings are feathered at the top
I said this for another Dragon pic I saw but this one had the same effect on me. It makes me envy creatures that can fly. But seriously this is a beautiful pic and she is a beautiful creature. I absolutely love dragons that have feather wings instead of the typical bat-like ones. Can't wait to see the comic.
