nice stuff man, good update. I really like the "noir" type office. I see a couple texturing issues that stand out right away, but other than that, I love your lighting in that one. You can't beat venetian blinds for some moody lighting.
As for the second one, keep going on it man, it's close, but I agree that the fish don't quite fit in. Also, the mines would be a lot farther towards the surface, and visibility through the water is just a bit too far.

Keep up the good works man, great stuff.
