Bwahahahahaaa...I totally agree with your friend about Citrine being best buds with Hematite! *Chortles*
Ah...ok. Just looks like the wing arm is angled up from the shoulder, then down at the elbow, and the wrist turned under and back. Looked uncomfortable! (Like I said, my mind playing tricks on me.)
Well, you're right, in that that IS basically how I've drawn it, but it's not really a particularly uncomfortable position for wings, I don't think - it's sorta how this hawk is holding his wings, except Citrine is doing it a bit more "openly."
