Watched through your AMV, and you seem to be rather good at this. The AMV got really amazing starting at 2:04 and only kept getting better from there on. Especially liked the timing on Eren charging in on Annie. The fight scene prior to that was pretty well timed as well with the flashbacks and such.
However Eren battling it out at the battle of Trost was the weakest part of the video I feel,and drops the overall pace of it. You may want to re-edit that scene as you can surely do better.
Overall, that was a really good AMV you placed forth and the later half of it really nailed it. +1 from I.
