^^ Stewie one is a bit too big, render too small, brushing is nothing fancy and neither is the coloring. Text isn't too good. Border seems out of place. 5/10 Anime one not bad, background is a bit bland, coloring is good, definitley an improvement text still needs some work and so does border.
6/10 7.5/10 6.5/10 7/10 sry. they arent really my type. i like the one of ryu a lot tho. maybe if u fixed it up a bit (seems too plain). then it would be better.
8/10 render has poor quality... not your fault 7.5/10 dont like how much the texture stands out in someplaces....
Russian: raidal blur, on both top is ok but not much of a background... buttom looks like it was done with some defaults top:7/10 buttom:7/10 both simple and plain... Sliver: plain aswell and change the format to .png or gif to show the transparent..7/10
