Better than what I expected!
I must say that I've been impressed by this flash!
The drawings are pretty good, maybe they are a bit choppy sometimes (I particulary didn't like the arms), but those are minor flaws that you'll soon solve in future works ;)
The movements are pretty good aswell. Not so good is the lip-sync, but nothing too serious. Also, some movements aren't that well executed, but most of them are ok. I liked the job you did with the glows. You only use them when necessary, good job with that!
The song fits with the flash, nothing else to comment about that.
Seeing some random and pointless fighting is always good if well executed, and this is the case, great job! :D
Looking foward more!
