Hello, first, you should tell them that this would have been better if they had actually registered and posted the mep themselves (well one of them anyways)
But anyways, not too bad overall but some parts are a bit messy.
Medaka's parts are too dark, you shouldn't hide the image so much, there are also a lot of lipflaps. The synch is mainly done thanks to flashes and blurs, which isn't good, it may look ok but it's actually pretty boring to watch, please try to make use of your scenes instead of forcing the synch with effects.
The Bleach one is ok but it causes epilepsy so yeah, maybe you should calm down on the flashes. There are other ways to increase the pace.
I enjoyed the Shana's
Kara no Kyoukai and FMA was cool too, good job guys.
So yeah, the mep was ok but it needs more work and cleanliness for the next ones, see ya
