Get RSMB, it'll honestly make your videos look far better/smoother

Both songs were a little messy imo but that's just my opinion, it's always up to you for that

A few screen flashes or shader changes would have been good in order to make it a little less repetitive (More stuff like 2:24)

If you want to showcase replays I'd suggest slowing the pace down a little so that you can actually see what's going on

Also for the intro/outro the background looks a little flat, would look nicer if you had a few layers and animated them seperately to give it a bit of a 3d effect
