it just LOOKS mirrored to me, like screams it...
otherwise its techincally good, but also, a few things that you should have picked up on.
his hairline is SUPER low, he has no forehead at all. when you look at it from the front, its quite easy to mistake the hair for a copper helmet.
and it looks very solid around his face, like one of those cocky dudes who gel their hair back that you just wanna hit whenever u see them.
the shadows around the eyes could be faded a little more gradually into the skintone
but ya, main issues are the hair line and the way it looks mirrored.
textring on the hair is awesome though
