yea, not good
first of all, this flash wasnt even funny enough to be a good random murder thingy, the murders were crap and the blood too stupid to be realistic, too crap to be anime style and generally crap. the clouds should have moved and the water could have been better. a kick and his heads gone? i mean wtf? the dude on the bars could have had his legs cut off or the waist so his legs hung.
the only thing i liked was the axe transition between the scenes,in fact if they were the only thing in this flash i would have given it a better score.
keep trying, you have potential, i like you character drawings. but in this case: BLAM!!!
