#31 Definitely the best logo so far. Great rustic feel and I like the colors! Maybe brighten up the colors ever so slightly (not much). Not crazy about the pears--something more inclusive like a combination of veggies & fruit.
#34 I switched out one of the pears for a tomato and brightened up the colors. If the pear still doesn't work for you, please let me know and I will try some other options.
#38 is looking good! What about trying something like carrots or squash or green apple. Root vegetables with their tops are on my mind for some reason.
As I continue to look at the design, I wonder if you could do a basket of produce in the same style you have created so far? And change the tagline to "all local, all the time"
