Sv it's nice to see you back into modelling i still LOVE your skinning, but you still got some of those issues your earlier models/skins had...
For one trunks looks more like a kid then a teenager and that's due to the size of his haid.
Secondly your models always kind of seem to be wearing a wig if you know what i mean. I think the problem is the hairline. It needs to be more natural looking and that shadow on the skin of the forehead needs to go, it makes the hair seem kind of floating above the head. He also needs sideburns.
I made you a drawover because it's kind of hard to explain so...
you see how he got toughness written allover him with just a mere proportion change
Oh and i edited the hair a bit with more lines on some places to make it look less like growler said.
Hope i could help, now get this babie ingame!
