Not too bad
The only thing that really stood out to me apart from what may have already been mentioned is that there were parts where the video seemed to linger; scenes that probably could have been cut/split a little sooner. It's actually something that was pointed out in my own video recently so it's something I pay attention to when watching others
The song is rather face paced and up beat as well, so the lengthened scenes kind of take away from the AMV a bit. Not at all saying it was bad though, kind of makes me want to watch the anime
Keep up the good work and keep practicing! I'd like to see more from you in the future!!
