For #72 I like this. I would like to see the image moved to the left, closer to center, but not totally centered. I like #85 more than #84, the way you've used colours. However the image as the "i" breaks up chiropractic too much and makes it difficult to read.
If you can resolve that with a vertical logo and maintain readability, I hope to see more! #72 in particular though I would like to see again, but with the changes I've mentioned above.
Also, I've been getting a lot of bright blues and greens, I would like to see some deeper, more serious colours tried.
#87 I move the spine image to the center between the two word so its readable #88 I narrow the space between the spine more close so the Chiropractic readable #89 Image moved to the left closer to center
