>>18475417 (OP)He looks healthier on the left, because the grey makes you think "old" but his skin looks decent, on the right you think he's maybe 40 at first but then his skin looks older. Also it's a rough angle and his face is in motion in the picture, so he's going to look a little worse on the right either way. Also the thinness of his hair looks fine with grey, but in brown, coupled with how his skin looks is much worse.
