It's cool, but I'm not much of one for tights lol.
It appears that his right arm ends in a mouth. That's an interesting concept. And may I ask what that weapon is? Altogether well done.
Nice catch there, I made it so that he had his right arm lost on the battlefield as a mortal, and when he became a demi-god, that weapon was placed to supposedly burst spiritual energy and form a solid usable arm again, using that energy. He can also manipulate it like a whip in a stream, so basically, it can do anything I can imagine him to do! :P
