I really like these, but the further wings from us are all bugging me i'm sorry to say. I think that there might be a perspective issue.
It looks to me like the wing closest to us is on an angle heading back from him, whilst the further wing is almost straight on from the character. I can't be sure if this is the case, but something about the further wing is off putting to me, perhaps something else is causing this problem I am seeing. Keep up the good work, I like what I am seeing.
edit* the more I look at it the less this seems like an issue
