you're probably getting "needs more contrast" comments, or comments that they don't like the toning. IMO if this was shot on purpose to be high key, it depends a lot on the viewer to "understand" the shapes in garlic. I will say that a bit more depth of field might have helped your subject stand out if you want to keep the high key effect.
7 - Good. Like the way you pulled it apart and chopped some up to 'showcase'. Criticism; a little 'blown' in my opinion, although I realize you may have been going for a 'high key' effect. Just more detail in the textures and 'sliced garlic', would have made this better in my opinion.
Excellent exposure control. I still see plenty of detail in the whites, and the tonal range is not lost between white and the darker areas of the pod. Good composition and sharpness as well. :)
