Hi, I'm new to this head texture making thing, and just made a few akutski head textures. I'm not selling them yet becuse I don't know if they are good enough to sell. Please give some critique on my head texture and if you think they are ready to sell or not. (please ignore minor blemishes on head textures, they are not really there on the game, but show up when you put them on spinning globe)

Why are they not spinning?

if you are gonna sell i would buy the 2'nd one, Pm me if u gonna sell it
