As far as technical advances go, you've definitely grown a lot. Your stuff is very pleasing to look at, and style instantly recognizable.
But, I've noticed you have a tendency to draw mostly big/buff characters in generally similar poses. I think you should vary what you do more. I'd love to see you try out different things. Draw some skinny dudes or females, try some spine-bending action poses. In this style.
Great K-rol sprite. I would love to see him in a Super Smash game.
I'm truly loving your sprites. You've grown so much artistically.
Ah, II remember kicking this guy's ass in the first Diddy Kong game thing for the GB Advanced.
Super nice colors and sprite, would be epic if animated :)
Dude...its awesome!
If you animate it i'll melt sexualy...
Good
