I agree with squidhime, the intro felt a bit lackluster since it was mostly the OP mashed together but then it got a lot better. I do feel like your sync could have been stronger though. I don't just mean your timing, but the parts of the song you're syncing to, like the "NO" at 1:52 and 2:03 would have been excellent for a roaring Eren or someone screaming. That would add a lot to your overall mood. I also wasn't too overly fond of the colour lights you used as transitions, not that they're badly implemented but the colour montage doesn't seem to match with the video because Shingeki's palette is quite...orangey and brown so the blue doesn't fit as well as an orange light would. You also used them way too often.
It was enjoyable though, that's for sure, especially since I'm a huge Shingeki fan. Good job!
