Entry #2 looks good. Is it possible to see what it will look like with the word Chiropractic smaller than the words Eastern Kansas like it appears in entries 4 and 5?
Entry #6 not too bad. What if we swap the font sizes of the text (between the "Eastern Kansas" and "Chiropractic") in entry #2? I think with that design, the text looks better lined up to the left like you originally had.
Entries #11 and 12...I like that you changed the font up. The one used in these designs look cleaner and not your everyday New Times Roman. In entry #12, I like how you gave the design a glossy look and how the "spine" is contained in the sphere and not through it like in #11.
