I'm really liking this! Just such a cool idea. My only thing is I wish the male character's wings were more... I dunno... more feather-like? I mean, I understand the contrast made between soft, warm and feathers of the female character against the cold, hard metal of the male... but if the metal wings were somehow shaped more naturally they wouldn't seem almost 2D. I hope this makes sense, but it's just my opinion and I still love this piece, so either way. Great job!
