I think it is pretty moodless. don't mean to sound harsh, but i wasn't struck with a "factory" feeling when i saw it. Modelling was nice. some of the edges were really sharp, and could use some champhering, but otherwise pretty good. textures on the machines are also pretty grey. needs shineys.

for lighting i would lower the ambient brightness of the whole thing (factories are dark and scary) and put spotlights on points of interest. Also, use a yellowy "dirty" tint for the light to make it look like a factory that has been there a while. Or red. rd would be good for heat lamps or something to dry the paint/harden the plastic/ whatever.

or you could do whatever. but definitely try to do something more with it, it is a solid work that has a lot of potential.
