I like where this is going. Maybe you could make more of a vignette around the celery, play around with the tones and think more about whether more could be made of the shadow. It's a cool idea and it's 99 percent there, there is just something I can't put my finger on which otherwise would make this image a perfect fine art print. Seems like I'm criticising but I'm not I really like this a lot. I'm just holding you to a very high standard because you are so close to making the perfect picture in my eyes.
