Ok I watched it and here you have some of my impressions:
-A fact that I didn't like was the presence of those black bars in the sides. If you want, I can extend you my 720p episodes of No.6
if not, try doing something with them because I couldn't fully enjoy the beta with them
-Ghost frame blending, I guess you already know how to remove them. If not, feel free to ask
-Lip Flaps? I dunno if the mouth movements were intended or not
-Synch: What are you exactly synching? The lyrics? The beats?
About the chorus here you have 2 options:
You can continue synching the lyrics as you did in the 1:09
You can try doing some hard cuts and a fast pacing editing and then start with the lyrics-synch.
The important fact here: The second 0:56 has a different beat from all the song, and the song obviously gets more upbeat, consider that when you decide to start working in that part because the edition there should be faster than the beginning, just my opinion
It's up to you what you'll like to do there, or if anyone has a recommendation is welcome
Now about my recomendations, focus mainly in the first 2, if you want to keep the same structure of the beta for the final it's ok, in this MEP I can allow several things
