He didnt drag anything into this thread. DBZhell merely said he thought his model was better than growlers in his first post (which he's edited out now)
Its not bad, but the ref you used for this is no better. Both references have their flaws, in yours, the whole body is scaled for a bigger build than kid buu's, in growlers the head is just a bit too big.
I'd also consider not modeling the teeth into the shape of the face, if you're going to model a mouth, do it so the mouth is inside with the lips closed, you wont be able take advantage of 1.3's mouth animations if you dont (when 1.3 is released). His legs are also a little too skinny his pants were very baggy in dbz, they maybe a bit too long too. You've also modeled him leaning forward a little too much, it makes him look a bit weird and it looks like its effecting some proportions, he's a little too wide from the side too kid buu was quite slim and wasnt build like a brick **** house, you should try to take that into account.
