I don't really know what to think of it. Some parts were quite interesting, while some others felt rushed or not under control. Well in any case, first of all just get rid of every subtitle or watermark, come on... It's really something we shouldn't see anymore. You also need to get rid of these deformed scenes like at 0:53. When you have a 4:3 footage you can't just make it 16:9, you need to zoom in and thus to lose a part of the image so that the proportions will remain the same and the image won't stretch.
There are a bit too many black fades, in some parts a simple cut would have been better. But it really breaks the flow of the video.
Also, in the end the animes don't mix so much. It's not a good thing, be sure that you don't have little parts of one anime then another part, you need to have all of your footage as a whole. And yeah that also means that it can be a problem when we go from fate to dragon ball or one piece for example, be careful about the charadesign and try to have the most homogene mixup possible.
It's a pity that you couldn't manage to get the same level as the part from 0:40 till 0:52 everywhere, I thought it was really cool and you should keep what you did well in mind.
But yeah a various is always a tricky work, so good job nevertheless and keep it up for the next one!
