This is just unnecessary nitpicking but the genre of the music in this MEP is Drum & Bass, not dubstep so you should probably change the title of the video lol. But anywho~
Well you have HD footage which is great (obviously youtube lowers the quality a bit but oh well). Everythings in the correct aspect ratio so that's a plus too.
The major issue here seems to be the editing itself. The shakes feel too "violent" so it's kind of hard to see whats happening. Same with the effects and cuts at the beginning. It just feels like too much is happening all at once so it ends up becoming somewhat incoherent and hard to follow.
My opinion is, you need to lessen the shakes, use one anime and I guess, maybe edit with a "story" or concept in mind (not always a necessity but it really helps with keeping your track consistent and coherent). Also keep the effects consistent as well. When you toss in too many effects in one go it usually ends up looking messy and conflicted. Hope this helps.
Good effort though, keep it up =).
