Only thing I'm disappointed in is they didn't make the beam blasts light up. Clearly they have dynamic lighting there with those enemies that are glowing and illuminate dark halls and corridors but they don't apply that to your shots or muzzle flash.
However, maybe that would be too distracting or completely change the dark mood they wanted for those areas because you don't have to worry about ammo in these games so you'd just light up the whole area by your shooting? I don't know
Oh, also, the first organic sandy areas could have a bit more extensive overhaul in some of the assets, the first big tree looked pretty chunky still and the camera zoomed right in on that, when in other areas they've made other stuff much smoother...
