I realized after I scanned these that the faces suck in every one

soldier

torso

streetfighter

kick

nice..you're really good at clothing and folds. the face in the kick picture..i think that because its such a small area to work with, its best if you dont try to give her features such hard outlines..i think you just want to give form with subtle shading. if you wanted to know why it sucks :)

plus her head doesnt seem big enough.

O.O Cool sketches!!!!!!!!
Here is a few quick sketches of mine, not nearly as good as yours but there still fun to look at.

Thanks staci...
I think part of it is that its such a weird angle too, hard for me to capture it right
I did the same picture on here and I'm still having trouble with the face
I'll have to try your suggestion

The head on the one here isn't big enough like staci said. I wanted to say it before but I didn't want to sound like I was just trying to be an ass. Also, the foot she's standing on is too far back so she looks off balance.

They dont suck!I think they are very well done!

I like the last 1 the best good job i love the way you draw on paper & computer. ^-^
