Hey Breaka!
I liked your vid, the crossover worked better than expected, you made a lot of masks and some ideas were really perfect, like the parallel between the two girls, the "fights" between the characters etc. That's also quite fresh, a crossover in fun, I don't really remember a lot of videos like that xD
What could have been better is firstly your rythm, it was a bit too fast for the song in the beginning, you used a bit too much of rough cam moves and the flow of scenes could have been a bit slower imo. Another point is that of course, some of your masks aren't really clever, but yeah that was to be expected, some needed more work on colors and incrustation and some were just a bit out of place because of the positions which didn't match that well.
But yeah, an interesting work I think, good job!
