Okay, first off. I'm tired of the motherfucking DOOM SONG, for christ sakes! It's like every kid who's ever seen Invader Zim thinks that's the funniest part of the entire series and takes it to heart to publically make jokes about it. Enough, okay? It's over used.
And that concludes the negative portion of this review.
Wait, not really.
Basically, you kinda just got the song and stuck a bunch of JPGS together. However, I'm a flash artist myself so I saw some pretty good parts, too. For one, good job synchronizing the words with the music, I guess. I despise doing that, it's so fucking dull. Also, I think I saw some of your own in-flash drawings (excuse me if I bashed anything you made with the JPG comment, but that's what it seems to be)and they were pretty good!
So, overall, not horrid, but still. I can guess you're not that bad at art, so use it to your advantage. Look for some websites about flash tutorials, there's even some on NewGrounds. Just keep it up.
