Ok First of all, It's really too long, 7min52... it's pretty impossible without a great experience or a great skill to keep the attention of the spectator.
Besides, this music is really hard to edit, there are a lot of different rythms and it's really fast most of the time so keep a good and clean editing is really hard. I think you made a mistake, choosing this song for one of your first amv.
Otherwise I can see in your amv most of the main mistakes of amv maker "beginner":
-bad resolution, you have to check the settings of your project and your footages are the same otherwise you'll have many troubles like frame glitches, bade resolution etc...
- Avoid all kind of logos and subtitles! It's very important!!
- Don't over accelerate your clips like this, much of the time you choose a clip and you accelerate it a lot. It's not a good idea, it's not beautiful and it doesn't fit with the music, you have to follow the rythm with your editing and not with accelerations like these.
- You have to be more strict with the sync.
- Try to choose carefully your clips. A slow clip when the music is slow, fight when the music is fast etc... you have to choose the clips you want to edit in terms of the music.
OK, Try to improve, correcting these mistakes, I'm waiting for your next work, I'm pretty sure it will be better!
