Umm, I'm going to say this again, you guys really need to work on that hair. Raditz's hair looks a lot like a SSJ3's hair, so if you look back in another reply that I made, it gives an idea on how to make that pretty well...
They don't allow images hosted on their sites to be shown on other sites, so it replaces the image with the hosted by angelfire thing. Same thing with geocities, and i think tripod. You should try http://netfirms.com or http://free.prohosting.com. I think those work.
I wont go find a picture of radditsu to nitpick, but..
It's pretty bad, in my own opinion. For one thing, radditsu was larger than goku..who's larger than vegeta. You're model's just too small..since you altered the vegeta model. I won't touch the hair, since it's been mentioned. The armor "covering" the shoulder's looks more like pieces of cardboard resting on the shoulders. The armor curved and covered a good part of the shoulder area.
The skin's pretty weak, too. The colors are drab, and it just looks flat.
To do the character justice, you'd need to start from scratch to get him right.
But, this is just my opinion.
It wasn't intended to be a flame, just some ciritisism.
If you can't take it as that, then don't ask for it.
