It wasn't bad
I really liked the style, the drawing and backgrounds looked good, but I think I can offer you two tips. Firstly, don't call your film "the ultimate short" it will just make you seem arrogant, and thus people will start watching the film wanting to prove that this is not the greatest short, and you will end up getting a lower mark for it, and secondly the web is full of animations with people fighting for no reason, don't get me wrong, yours looks nice, but I've seen too many to remember yours. Try doing something new, something that isn't just two people having a fight, personally I would prefer you to make a short that is 90% plot driven, but if you really want to make a fight scene, give ti some story, and not the usual... you stepped on ym foot, so we shall fight to the death crap, have a proper plot. Do that and I'm sure you can go a long way. I wish you luck with your future ventures.
