Well... here we go.
Well first off, your animation style seems to be you can draw and animate well, but the way you color. I can't even describe it. Maybe it's just my taste in flash, but I don't like the fact that you use very faded out colors. They look horrible. And some parts look like you just scribbled.
Suprisingly, I had high expectations for the animation. I loved Halo Reach. It was a good game and a great way for Bungie to end the series. Unfortunately, when Egoraptor's animation came out, I was slightly disappointed because I like parodies of videogames, I just hate it when the person who is parodying the videogame doesn't actually make fun of or mock the aspects of the game, but rather chooses to have random unrelated jokes that don't relate anything to the original product they are intending to parody.
When Egoraptor's animation came out, I was disappointed because he didn't make fun of the game at all, just random unfunny unrelated events that didn't tie back to the actual game he was intending to mock. But when I saw this on the front page, I was hoping that you'd actually make an effort to parody the game, rather than fall in the same path as Egoraptor with the shitty random jokes. But I was wrong.
I wouldn't even consider this a parody, the only aspects that actually relate back to Halo Reach are that there are Spartan characters, and there are Elite characters. But beyond the exterior of these characters is nothing more than cheap, lame, immature humor that only a 12 year old would find amusing.
