Alot of times factories look like dingy dismal places...you sure gave this one a beauty treatment...wonderful colors and I love the sheen coming off the metal and pipes...great work...favs.
Normally this is the sort of image I would call "overprocessed" but assuming you were going for an "unnatural" look with this I think it works quite well. Almost looks like an illustration. I would even go so far as to call it slightly surrealist.
Well done.
