I'm sorry, but....
Bad points:
-You used too many screenshots and game art, it seemed as though your were getting really lazy on us. Come on.
-It would be better in full color.
-The animation was too ordianary, nothing special, nothing new, nothing WOW.
Good points:
+Your singing has improved! YAAY!
+The lyrics are okay, I found it repeating things over and over again. I felt you could be more creative (i.e. make references to other media, rather than just Halo, excellent parody artists do that)
I felt as though this animation was nothing different from your other video game music things. The only difference was that your singing has improved. You'll never get better if you keep using black & white characters, simple animating skills, so much game art, and not-that-funny lyrics.
