Some pretty good ideas in here, in particular the drop is quite strong and feels entertaining, scene selection for the most part is nice and nothing feels too much out of place.
As far as technique goes I would recommend you to pay more attention to your masking/keying and transitions, since the slower parts of the video suffer due to this. As Luna points above, it's probably better to skip the mask/composition altogether if it doesn't look realistic, as it breaks the mood of the clip. I would've also liked to see a colour scheme here, I think it's quite important for this type of AMV since it'll help you tie in all scenes into one cohesive universe.
It's a good start nonetheless, keep up at it!
