The broccolli is some areas is to blurry for me. It bugs my eyes. Maybe try not to get is so close and use a white background instead of black or blue. (?)
Bad depth of focus. See how the middle part (on left) is in focus but the front and back aren't? That means your fstop was 2.8 (or lower if that's possible). Watch for that especally when you zoom way in.
Lots of dark shadows on my monitor, and the broccoli looks more yellow-brown-green than the bright green I would expect. There seems to be a very small area that is in focus, and the rest is pretty fuzzy. I do like the way the lighting lights up the stalk areas, and the little buds.
