That is sooo funny but also very nicely done. Feels to me like the roll should be just a touch further to the right within the frame but composition is strong as is too.
Maybe the perfect title for this would be "Oh Shit" This happened to me once in a Home Depot and that is the first two words that came to mind. That would be a funny title. Ok back to the photo. Overall I like it and think it is a great photo. The only things I don't like is how the floor is blurred toward the bottom of the photo and the other toilet is kinda distracting. If you could get that and the roll in focus I think this would be a perfect photo.
I really like this shot-can't help thinking that it might be better for the person in the stall to be the one receiving the roll, or it could get messy.
lol.. that sucks! if he yanks on it, it's just gonna make the roll go out further.. good thing the ground is clean! nice use of shallow DOF, as the important line is essentially implied, and a wider DOF would lose impact via distraction by other elements.
Your DOF is great in this picture. The overall feel is very urban and clean, but this is not an image I think I would keep coming back to. Close, but there's just something missing to retain my attention.
