Wow, impressive ! I love the new lighting, and so many things ! it looks amazing.
I loved map02 too , the hommage to doom1 E1 maps ^_^.

10:12 : I just love this room <3

Some improvement suggestions.
15:32 : some missing brightmaps on neons?
17:54 23:0 add some subtle green lights near acid pools (really subtle, not too strong).
20:14 same as above + darken 50% acid smoke to lower the blinding additive saturation effect. 16:42 19:45 22:15 -the outside areas are a bit too bight, or it's the sky that is too dark : because they are brighter than the mountains and I think they souldn't. Shadowed areas hereĀ are too dark, the sky/sun light would bounce on walls and floor, making shadows brighter
24:55 add lights near bubles tubes?
25:25 : light from outside will bounce inside making the sectors close to outside brighter
25:35 the revenant alcove being narrow receive less light than the big center area, darken this sector (makes it more readable)
25:45 less light is reaching the door, this sector could gain being darker

I don't know what would be the result, but maybe try darkening + adding lights with big radius in the sky to add some lighting gradients in those outdoor sectors?

Anyway, great job !
