My main focus was (Get ready for shock) THE TEXT! dun dun dun!
I see people use Halo text all the time but the truth is it looks like crap because well.......its plain, so i spent some time figuring out how to make it look like halo text and it worked

Then i burned the corner where chief is standing and used some brightness and contrast, then i got rid of the white crap all around MC, then blured the edges a bit and vualah!.
Thats it really, i wanted it to convey Halo 3 as much as possible so i didnt use any brushes, i just used a h3 preview image for the background.
