#3: I like this the most of your three entries, but maybe too much emphasis on massage part. I think no space between SolYoga might work even better? I like the text being on the side.Maybe it should say Yoga teacher and masseur, instead of teacher and yoga masseur. Or maybe try yoga teacher, yoga masseur?
#2: Doesn's quite work, especially the green bit seems out of sync somehow
# 1: Not bad, but the letters and image are not so much in harmony.
#6-8 are becoming too complicated with the extra posture. None of the poses really appeal, perhaps something more meditative, less physically challenging # 6: the text here works fine, but I think the space between Sol and Yoga is probably better (as in # 3)
