well, i c it 2 now, looks good, but the head is way 2 big for the body, if you want to build an realistic muscled villain, you should make the waist small, the cheat large, and long legs, and the head should fit in the body length like 7 times, i dont know if this is correct, i just learned this from a book.
btw: isnt that char just a mix of: frieza, cell, buu, bebi???? and 1 other i cant name right now, (its on the edge of my tongue)
