not sure if I am a fan of the nose and wrinkles adjacent to the nose. seems too wide ingame. but then i shrank it and played with it a bit and it creates a different expression so I dont know.
perhaps brighten up the beard in spots to emphasize the jawline
shading on the skin near the ponytail creates a weird depth ingame. I think you might be able to bring your brighter skin tones backwards from the ponytail to the ear.
So #3 I really like because I have a fondness for beards, but I think the last issues are the ears and the ponytail.
I'd suggest drawing the ear and the hairtie on a 1024x512 canvas, resizing it to 512x512, then redraw them on the 512x512 to get better mapping and quality.

Thanks for the comments fellas. I really don't feel like making too many adjustments to that bearded dude anymore so I'll just keep that stuff in mind for future endeavors.
Chaco: The rest of them are just generic doodles. For the one you bought I was inspired by some sculpture of an alien AgentP found on one of his classy websites or something.
