Computer's sent in for repairs so I decided to do something with my old Windows XP Desktop. Haven't studied anatomy, so I'm not surprised if it came out terribly.

Made in GIMP.

It looks decent. It's not the best i've seen so far in this style, but that's just because of it's simplicity I guess. Maybe you could add some more details to make it more good-looking to a rock texture. The only thing that bothers me are the eyes. They're too rushed/cartoony imo. Keep practising!

I agree... You could keep it this simple but if you r then I would work on super close up features like face lines... And age marks
