Here it is at last!
The second, and hopefully final, Covenant Grunt costume from the Halo series. I made one in high school, and thought I'd redo it, since my cardboard-sculpting techniques have improved in college.
Took me about a month and a half to make, mostly because I put everything off till the last minute.
I tried entering a costume contest but that turned out to be a complete joke. But the amount of "oh my god"s and "that's the best costume I've ever seen"s totally made up for it.
I was amused at all the people who thought I was a man. I sure fooled them! ^_^

For comparison, here is my first attempt at the Grunt costume, circa 2005: [link]
Cardboard; paper tape; hot glue--for the armor
Cardboard; staples; fabric; stuffing; copic airbrush system--for the skin
Liquid latex, bald cap, cream makeup--for the face/head
Cardboard etc and respirator for the mask.
