The best thing to do is look at Hanz0's hands, he makes great hands (infact, TTM [the elite texture artists] used to use his hands as templates!).
You can download his set by using "/dl hanz0" ingame, then navigating to the '/toribash3.9/custom/hanz0' folder and looking at the textures.
REMEMBER: Use them as a learning tool only, do not steal or plagurise other people's textures!
