Minimoto: I agree with Aimo, I think it should be faster, some places are too slow and some are too fast, for example 0:9 is way too fast, from 0:15 you should sync more and the mask should disappear, I mean that you should fade it out (and not remove it entirely), so when it appears that's okay, but when the background comes, you should fade it out in the meantime, I think that would look nice

from about 0:19 I think that the appearance of the scenes are too sudden, you should make them a little bit longer, and somehow avoid the hardcuts or something like that (e.g. you can just make 2 layers one with the green haired and then you put the other clips above with lower opactiy and fade them in and out or something like that, it's up to you

and of course edited as you want to and not like I would want it, it was just an example that I think would look good xD)
or as an another solution you can leave the hardcuts as they are, but longer the clips and it will look better imo, and yes, the blurs are strange

but I really like the scene selection, that's very nice

also at 0:02 (or 0:03) the scenes are too fast and at 0:11 I'm not sure if those scenes fit actually (it just shows many characters)
