Decent MV overall, I definitely see a lot of potential in you. Some of the things you can improve on are your clip selection and effect selection. You shouldn't have used low quality clips especially some that are tagged. Also with Sony Vegas you can make the video fit the Youtube player so you should try to do that. If you don't know how then try
https://www.youtube.com/user/techtopia , he has alot of tutorials on the basics of Vegas, and he'l help you understand it. His tutorials helped me alot when I first started with Vegas. Also you should try to not use random effects, though I understand why you used them. Try not to change effect from clip to clip. Overall this was a good video. I'm definitly impressed by it and hope to see more from you in the future.
