I must say... There is waaaaaay too much for me to comment on, so I'll refrain from stocking up another post with tons of images.
Crimmson, excellent work, man. I love the way you were able to model some of these from concept art and images with excellent precision, such as the Soldier torso, Prefect armor concept, and I swear that the Pioneer helmet looks so much more detailed than the original in-game model! Nice work on getting some of these pep-ready, too.
I had a question, as everyone who has played around with the assets recovered from the game still have yet to acquire complete data for the multiplayer armor (apart from Recruit and Scout), would you be willing to take requests for armor models? I'm thinking Enforcer, Mk VI, Mk V, ODST (shoulders, torso, arms and legs), Prefect, and the cut Hayabusa design, to name a few.
From the Infinity armor pack, I realized that certain parts about the ODST helmet were really bugging me, mostly because of the excessive smoothness and lack of detail it should've recieved, as well as the chin-guard appearing too much like a Recruit helmet.
But back to what I've said before, you're doing awesome work. Kudos, yo. Kudos indeed.
