It was pretty okay for your second video, but the biggest flaws I saw in this were that you used too many cuts, making my eyes restless which doesn't quite fit the songs you used. Using cuts is perfectly fine and can get rid of some boring stuff in videos, but never overuse anything. You could've also gotten rid of the hue changes since there wasn't any real point in using them but seeing your clean stuff is pretty nice compared to many other editors' videos out there.
Also a tip for something you should do next time you're making a video: stretch the clips to be 16:9 to fit YouTube's window size and that of most of people's monitors and try creating a clean simple CC so you won't have to deal wih SA's standard boring colors.
Well, keep on editing and you'll become fucking amazing. Good luck.
