This looks awesome, dude!! Trunks is incredibleasdafhasdbvabhsva. I also liked him with long hair and Vegeta's armor in the Cell saga and I also kicked butt with that one in Dragon Ball Z budokai tenkaichi 3
There is a problem with his wrist, the one not holding the sword. I believe it's too bend or something (not an expert) The pose on the left, he looks a bit like an angry girl or worse... It doesn't fit the sayan class well. It looks a lot like a CG art for a video game and not for a movie.
But now, the good parts : the hair are awesome as is the face and the sword, no change to do here ^^ Oh, and I've watched your animation, they are cool, but have a kind of "puppet" effect to it, like a shot from Wallace and Gromit, I don't know if I'm being clear here.
But I love DBZ, so keep it up I still love the art anyway
