It's alright.
Overall, this piece isn't that bad, Though your pacing is a bit too slow, your sense of visual drama is pretty good. The gun flash in Batman's eye was pretty cool. The animation when Batman hits the guy and takes his mask off was excellent! Graphically Orgasmic!
Even the cops getting hit looked nice and smooth. Very sleek
My only criticism of this piece is that you really need to pay attention to what you're doing, information-wise.
You misspelled "Gotham",
and "Batman" is only one word.
I look forward to seeing more from you and watching you improve from project to project in the future, soon... youre stuff will be award worthy. Good luck!
