Lots of really compelling stuff. I am leaning toward simplicity, and feel #70 and #68 get closest to the heart and soul of what we are trying to do. I am not sure lightning is quite right, though. No green, please. I am not drawn to the moon and lightning bolt combo. also, #51 and #50 are using a spine form, which we are trying to stay away from. Not sure the font you have chosen for "chiropractic" works in the larger size as seen on #70. I am on the fence about that font choice overall, but good strong first showing. We are looking for good high contrast here to stand out on a long commercial block of signs. I am excited to see your next entry. Thank you so much!
#111 and #112 are really great! Not sure I dig the font you rendered for "chiropractic." I am starting to lean toward a single line between the textual elements. What if just the "w" had color?
After all that, I think that #112 is still my favorite, although the font is better in some of the newer versions for "chiropractic." Maybe "chiropractic" in white? Maybe larger.
