Mudbox More Adventures

Just out of the blue I just started messing with one of the templates on mudbox and well, I started liking where it was going, so here's what  i got going so far...I'm trying to decide what kind of dude this guy this should be... soo many directions, once I figure something out, I'm going balls out,....for  now, it's simple muscle structure...

Here's the back of him..

What should I do? Should I make him a fat dude? a zombie? a self portrait? Vick Macket from THE SHIELD? I've got a perfectly good virtual made body and I don't know what to do with it. I'm sure I'll think of something...
