Good luck getting your channel off the ground, youtube let's plays and reviews are very competitive so I hope you find an audience.

A tip though, it looks like you've filmed yourself in widescreen and captured your video footage in both widescreen (in the title sequence) and 4:3, but then you've processed it all into 4:3. The result is the two black empty spaces on either side of your video and more black empty space on top of your widescreen footage. I did that on my first ever drum cover I uploaded as well, so next video you do you should be mindful of that and make sure it comes out in widescreen, it'll make it look much better
