Not completely bad
First off, let me get this out of the way, I hate The General, it seems to be the only song anyone knows from Dispatch. Admittedly, it's good, but they've got better. But that's not the reason you only got four stars.
First off, the audio quality wasn't very good, and it's not my computer I know that for sure. Secondly, the first part looked like you at least put effort into it, but afterwords, yeah, it just seemed like something you threw together in 5 minutes.
Try to improve on your skills, and please, try to come up with something with a little more originality. And before I forget, I like to think there's a reason that Dispatch doesn't have music videos, they want people to interpret the songs in their own way. But that's just my opinion.
And if anyone hasn't stopped reading/hating me after "I hate The General", I really hope you'll take what I said in mind when you do another flash, I really do look forward to seeing what you can come up with
