I didn't really like it :/.
First I'm really not a big fan of this music, nor of mecha amvs, so this didn't help ^^.
I think the pace was a bit off sometimes, and you had some static/slow scenes (0:57, 3:02 for example); especially on the first part, I liked the second part of the amv better: it was more dynamic and the pace was better imo.
And the main thing that bothered me is that it lacked impact: the editing was too linear (a lot of cut transitions) and I didn't really understand the story if there was one, so it felt a bit random to me since I don't know the anime.
Good luck for your next projects
