Only thing I would mention is, I prefer the styling on both right side shots, the ones on the left seem really weird. Right ones seem really natural, like abandoned on the floor without care. The left ones look like flat people are wearing them and look a bit creepy. But that's my bias, of course, I don't think anyone wouldn't buy them because of this. If your client likes it, that's all you need. Good work.
