i like them a lot. the only thing i would say is please tone down the radiant bloom effect or whatever you call it when everything looks like you're seeing it through the eyes of a person who just woke up in the morning.
also, do you remember how frankie was bragging during H3's beta that the air has particles now so things far away look kind of foggy? please limit that as much as possible. i loved how halo CE was crisp. i don't know if that word translates properly, but the environment just felt crisp, in a good way. I know you love sticking little details everywhere, and blooming and fogging your way to realism, but it starts to look cluttered. keep it simple and crisp. thanks for listening.
oh, and really, everything looks beautiful as is, i'm just giving you my suggestions to make it even better.
