Awesome work! I like how the video was broken down and that you explained why you're doing some things instead of others. Since you asked, I'm currently working on a Halo Spartan cosplay, and if you're interested you can follow it's progress over on my channel as well :-)
Glad you liked it. It does take a while putting tutorial videos together as you probably know. Oh awesome, I haven't played Halo for years (more of a playstation gamer) but will check out your channel as that sounds like a very cool cosplay.
