i can see what looks like either jpg compression or excessive sharpening artifacts on this photo. Perhaps shrinking it a bit would have helped hide these
Composition is good. For the peach to be the main subject it could possibly be exposed by at least 1/2 stop more. Also, the focus seems to be behind the peach.
Lucky you to have such nice fresh peaches. I think the picture is a good one but I think it could be imroved if you used a flash to highlight the peach, and put more focus on the peach as well.
I like the humour here: the fuzzy focus really matches the fuzzy peach. Nice. Only the challenge says that no flowers are allowed. Isn't fruit the flower of a tree? 5
