First thing, I just finished my Piccolo not to long ago. Last Week
. One thing you need to do is post a picture of the front and side, because it is so much easier for people to crit on your model. And if you post front and side you might get lucky and people like Super Vegetto, Kreshi, Kama, and them will do a drawover which helps out a bunch.
Anyways his legs look like they need to be longer, and maybe his crotch needs to be brought down a bit. I feel your pain, texturing is kinda new to me to... lol
