This is a good start. You are doing great but there are things that could be better. Your build though, it's freakin perfect for Vegeta!! The hair is way hard to do though, so no points taken off for that haha
I saw your SSJ4 one on here on the front page when I got on today. I freaking love it man. Looks extremely amazing and you get mad props for doing a great job.
Now the critique if you don't mind. Only ONE thing to say here..The shirt..While it looks fine, it's a little loose on you. It's very noticeable which takes away from the fact that it's suppose to mimic fur. It looks like velvet, which is a good choice for it since it's suppose to be really REALLY short hair, but getting one that fits more skin tight would look much more realistic.
