I enjoyed it but...
I'll have to agree with Hydecka on this one, you just need to work on the graphics. But my only advice for the future is to work on the story a bit more. Don't get me wrong, but at times it kinda gets confusing, as wheter or not Comet is a bounty hunter, police or vigilate (if i spelled that right). The violence was ok, but you should try to animate the action scenes (when they're shooting eachother) rather than put up a flashing screen. The music was ok, but I'd rather like to hear actual voices for what they say. Overall I only gave you a 7, but you may very well be on your way to a 10 pretty soon.
P.S. I'd consider not making these in episodes (i.e. Ep. 1, Ep. 2 etc.) because they don't really fit as a series, but that's up to you.
