great work sking, nice and detailed models, good mixture of objects so the don't look to repeating.
I really like the foil wrapped cargo, did you used images for that or modeled that stuff??
But please don't torture us with that massive JPG compression, it makes my eyes bleed!
I prefer longer loading to another visit at the doctor
Regarding some hints I can only point you not to use such (oversaturated) colors like the yellow and red metal parts in the hall. keep max values in RGB @ 204 for a more natural saturation.
For the shiny floor inside the hall try to use some exponent map (high in contrast) to enhance the look.
