also.. ur in the wrong place really.. there were 2 dbz mods, esf and dmz.. dmz died out, and esf's team is kinda full
there are other dbz mods out there.. but i doubt any of them will ever even release..
also, when u say "artwork" u can mean the following sorts of artwork: mapper, texture artist, modeler, skinner, sprite artist etc.
u should specify what sort of artwork you are willing to do.
