Jerk's spriting attempts

[chase123]

You make very good sprites

Just saying 'you make good sprites' won't get him anywhere in spriting,you should also suggest the bad parts about them.

I'll begin:
1st sprite:
Looks good,but the shirt and pants need to look less blurry.

2nd sprite:
I like that hair,he looks a bit stiff,everything else is well done though.

3rd sprite:
I like this one,the pose is quite good,but I can't quite understand what is on his face though.

4th sprite:
Well you tried experimenting at a larger size this time,and this looks quite good.
