Hey! Here's My Review!,
I like your background because it's custom and it is unique to you, the black makes the purple really stand out!,
I think you could improve your 'About Me' section, as it doesn't have much information about you!, you could add things such as what type of videos you make and what videos are coming soon!, also add some information about yourself in there too!,
You have a heap of videos which are 720p, your videos are amazing, especially the editing! (well that's the whole point; the editing), the music you put behind your videos are very relevant and get my heart beating!,
One of the only things I'd change is the length of your intro, since it's a little long, maybe try to cut it down to 5-6 seconds; although this is not highly necessary.
Hope I Helped
