Sorry if it seemed like I was picking on you, Bo.  I was just trying to help out.  I'd expect you to do the same to my art, of course. 

In the fighter sprite, there is no evidence that he has a mouth at all--no visible teeth, lips, or mouth line.  In the portrait, there is a big lower jaw, with a different shape than the fighter sprite, and a full open mouth with tons of teeth.  You can't tell me that when he closes his mouth, his entire lower jaw and all of his teeth get tucked neatly away into his upper jaw.

I think that Sora one would take me a month to color.

Thanks 

I really like what you did, I will make sure Ill have a look at them, take them into account and reshape my figure
Only thing I don't really like is what you did with the face, I preferred my version of it

That's perfectly OK, I was just confused as to why you put the mouth so high up on the face, because his jaw looked a bit big to me.  But it's a matter of choice.

And sorry for not explaining the changes, here you go.

First change:  Fleshed him out a bit, and made him look more 3-dimensional.  In the animation (thanks Monsoon ) You can see him bulging in and out.

Second change:  Made his pecs a bit more evenly sized, and fleshed them out too.  Reduced his left shoulder muscle, it looked like a tumor.  Made his legs connect further down, to give him a pelvis.

Third change:  Forget it. 

Can I also suggest that you use less colors?  If you have two colors that are very similar (I saw examples of this in your work), make them one color.  It's sort of a waste.
