Very nicely done indeed. :-)
Y'know, once again I'm amazed by the amount of effort put into a game dedicated to beating up people who vote *bad* on movies on here... the irony's almost precious. ;-) Anyway, I was very impressed, actually; the graphics were good, nice smooth animation, and the 'Rocky' soundtrack was a nice touch. Excellent work.
As for new hit zones, you may consider:
1) Ears
2) Arms
3) Legs (if you expose more of the victim, that is)
