I like the layout tweaks and the ice chunks over BR tower that can be shot down (kinda like Waterworks). Shotgun hallway looks really cool as well. However, the general lighting of the level just looks... off. The sun casts this unnaturally tan/brown-ish glare over everything, while the original is blue and the lighting is easier on the eyes and seemingly more natural despite the blueness, with no weird alien sun glaring down. Compare this:

With this:

Maybe they're using a modified Halo 4 engine for the remade maps, because the lighting and color palettes have a very Halo 4 vibe, and I'm not a big fan of a lot of Halo 4's general aesthetic. It kind of reminds me of Haven, which also had a dull, muted, bland color palette.
