Count me as one that would like either more DOF or less objects in the picture. Your detail on the shroom is good and you might play around with some tighter cropping.
I gave this a 5. I like the subject and the DOF is fine. The lighting on the mushroom and onion is good, the other white veg could use a little more detail. I think it would be improved by moving it all off center and not cropping so close to the top of the onion.
I think the lighting is good. I might've done it in the portrait orientation with more neg space beneath the mushroom. I'd up the selective color: black so that the background is a bit more solid.
