Nice attempt at the challenge. Just one question why is that one towel on the bottom left not as neat as the rest. Amazing that is what stands out to me is that one towel.
Your lighting is a little off you have some shadows up at the top of the towels.
You have a decent amount of texture here so that adds some interest.
I would consider cropping this differently though that dark wall does nothing for this photo.
As someone else said one towel taking up most of the frame would work. It would come off as a stronger image then.
Nice shot! I think it could be even better if you took just one towel roll and placed it on an all-white background with it filling most of the frame (maybe about 2/3 of it). And also use some soft light to eliminate the shadows.
This is a good idea for the challenge. I think that if you could have photographed the towels more straight on to eliminate the brown on the right, the picture would have had more impact. Nice texture in the towels.
worked well for me, just don't like the lack of light at the top of the pile. Both the transition and the sharpeness of the transition in the light distract me from the image itself.
