It looks like the focus is in front of the tomato...I couldn't tell it was a tomato without the subject. The bright reflection and water? spots are distracting. I don't like the square composition either. Sorry.
The water droplets in the lower left look like they were the focus point for the camera. I think that tightening up the focus on the tomato and working on the framing would greatly improve this picture
It could be a tomato, yet it appears to look more like a red gumball - to my untrained and non-vegetarian eyes. I also keep looking down at the water droplets. They draw my attention away from your main subject.
