Well done. I think you cropped it a little too tightly though. I want to see the complete bulb in the center but it was cut off on the bottom. I find the crumpled, dried leaf on the stem distracting but others may not.
Pumpkins without being pumpkins, I love it. The composition bothers me a little, but I can't suggest anything different based on this shot. I think it may be a little bit too tight -- especially along the bottom. It may also be the fact that the central "lantern" is neither centered nor very off center -- does that make sense? Honestly, I'm not entirely sure, I'm just trying to talk out some of the things that may be causing this feeling that "bothers" me.
