maybe some adress, like clothes for mage, or effects, like sparkles, more horn options. maybe hair options, like a snake hair or something like that. i'm a coder, not artist, so i don't know if this is possible or has a high difficulty. u can turn your models to 3D, and make the animations by blender, will be much more easier... and u can aplly physics and collisions or even some python addons.
