You are really good drawing and coloring. :P However, I will the edges are big jagged in the first two. o.o" Also, the colored Pein and Konan eating food, around the edges of Pein... Shouldn't that be colored? ._. Other than that I cannot find any issues with them. ^^
Did you draw it digitally with a tablet? or drew it on paper then scanned it? o.o"
