That was really perfect
Not much to criticize, your animation style cam through perfectly, and I honestly can't think of one thing to complain about, aside from the normal, I wish there were pause rewind fast forward crap.
That was awesome, but the thing I enjoyed most was the voice acting, it was so clear and perfect. That my biggest problem with flashes that have a lot of potential so it's good that you obviously made that a priority.
Great job, and I don't even really like superhero stuff :D
