1,3 and 4 are overexposed, with the 1st and 3rd being the worst. I think it almost works with the 3rd shot, but the highlight above your head is distracting.
I think the strongest of the 4 is the 3rd shot. Watch out for objects, such as that pipe, that can ruin very good shots.
If there is anything that I would say, its that they are not really "compelling" shots, which I know is quite vague. Try mixing stuff up, maybe take a shot, look at it, and try to work with what you like and try to remove what you dont. keep it up though!
