Tzina,
I like your style very much. Below is initial feedback. My partner has not seen them yet so I will respond again after he has a chance to review to let you know what he says.
#7 & #11 - While I think these both look very nice I don't think you will be able to read them from a road sign with the script font. I also have concerns about the solfness of the colors. Pretty, but they need to be able to be read by cars passing by.
#8, #9 & #12 - While nice as well, however the outline on the font concern me with being able to read them on signs. Also the leaf inverted to look like a heart looks better than turned down. It looks more like a leaf than anything else. We need to convey an overall wellness message.
