More practice on Body structure if not you are doing it kinda chibi style. Since these characters are around 4 heads tall.
Obito's legs are too short, but other than that you did a great job!=D
No, I was trying to draw them how thet normally are xD
All right! Keep in mind that realistic manga characters are around 7 - 8 heads tall on a male character, but then again I guess you already knew that :3
