My latest work, please give me honest opinions. This is probably my most detailed scene to date, so would like to know what’s good and what’s bad about it so I can improve for my next 
Just because you can’t see it in the picture, heres a close up of the dust effect on the lens
Good idea, I like the concept, but somehow i thought the red cushions were a pipeline of some sort. Also the dust effect seems a little uniform?
Thanks for the opinion, I can see why the weird seat shape might cause this lol and actually surprised about the dust problem, i used a layer of stars to create them, and they definitely were not uniform? Ah well 
It’s a cool concept, i like images with strange gravity. This reminds me of a subway so my immediant reaction is that those types of chairs looks out of place, however uppon further inspection it looks more like a waiting room.
A bit confusing at first glance imo and the vignette could be toned down a bit. Other than that, good work and keep it up 
I love the concept
3 things though:
- Lighting is bad (no soft shadows) - put an area lamp just below each of the lights on the ceiling and make sure you increase the samples.
- Textures aren’t very detailed/natural, and that’s what adds the awesome factor to every scene.
- Vignette is WAY WAY WAY WAY WAY too strong
And some suggestions to improve it (IMO):
- Experiment with more drastic compositing (especially with colour balance) to create some mood and drama - apart from colour balance I think it could do with a lot more contrast and some glare on the lights (don’t go crazy with the glare like on startrek, but a decent amount would be good)
- Move the tunned where it starts to twist up a bit so you can still see the floor - it almost seems like the twisted part is layered on behind the foreground - the path your eye travels is cut off there.
