yeah i completely agree, the more I look at the transporter room specifically it looks very cartoonish, really oversaturated especially on the walls, I think I'll work on that next.
Yeah lighting is surprisingly frustrating to get right, the brightness issue might be because of a bloom effect that I enabled in the engine, I'll try dimming all the lights a little and see if that helps :-D
As far as source images go, I'm basing the proportions off any set floor plans I can get my hands on, have a floorplan for the whole of Stage 9 so that'll help when I have to tackle Engineering.
So yeah, floor plans and any reference shots I can find, I'm finding the new TNG Blu Rays to be a great source for this! :-D
