Pretty Madness like, fluid animation. I like the weird portal cracks and the transitions.
The sound on the guns is very low quality, though. Also when he takes two shots in response there, there aren't any bullet holes anywhere. I don't know if this is a sequence of any series so it also leaves me pretty confused.
So yeah, some more attention to audio quality and consistency on some things here and there and this might as well be the real thing.
