Awesome stuff! I seriously hope you can do some more for each level in the game, these are going to be really helpful for some posts for the lore thread that I'm working on (especially Covenant stuff from the cutscenes like Sacred Icon, and in-game stuff from Delta Halo/Regret and High Charity's environments on the levels Gravemind and High Charity)
It's amazing how much of a difference there is between the Xbox and PC versions when cranked up to proper levels. Here's hoping the image quality of the classic version in MCC is closer to that standard.
