Oooh~
I think the replays you chose were absolutely perfect for this, first off. They worked really well with the song and you were able to get pretty creative with them.
One thing I did notice though was that sync was a bit sketchy, mostly because the song you chose didn't have a whole lot to sync to. The song had a super weak bassline in the section you chose, with only one beat per measure (as far as I could hear). So you filled in the extra space by trying to sync to other parts of the song and it ended up looking a little messy.
