track 1: same as MDL said + the bass line 0:31 could have been a good moment for beat sync or an effect, since the track was kinda slow.
track 2: again like MDL said, some parts weren't quite clean cause the pace is really too fast in some rotos, it's hard to appreciate, internal sync would have been cool.
track 3: 1:15 the roto transition isn't clean in term of perspective and coherence. the eye zoom at 1:21 was cool, though. the pre-chorus was quite powerful , 1:27 to 1:32 was much more agressive than the part at 1:25-1:27 which fits a lot better (hero alone, boss with his minions...). nice last image with the mic. :p
track 4: some unperfected flashes. the rotomask on the cloud felt a tad odd, maybe just have roto'd the character+foreground, then use blending mode to create more immersion with the sky and clouds ? the anime fits a lot the track.
track 5: felt it had a bit more of "opening lazyness at the beginning", but you made the crescendo quite well ! good intensity .
in such a short timespan, i think you guys are getting better over time. i'm really curious to see what you'll do on the next one with a bigger time limit, cause even that kind of birthday/rush mep felt nice for me, haha.
