Really strong right out of the gate. Thank you. Maybe the flourish is a little too feminine. We wanted masculine/protector/fatherly, but please don't delete this one...it is compelling. Green is not a preferred color. Good, strong font, I think. Want main strength in the text.
#13 and 14 not sure of colors. Maybe a bolder blue. Maybe purple. I like the font, although would like to see "chiropractic" match up in size with "Great Works." I still think the flourish is a little too feminine, even in different color iterations.
I see....with the word chiropractic stretched, it changes the whole look and feel. If it were to be of equal font size, would that work? The other entries are nice to see, although I am not sure I'm attached to the flourish. I like the blue in #15, but maybe if it were a little bolder, almost going into the purple scale a little....what I think of as liberty blue. Any other symbol ideas?
I am going into the final judging phase. I had your design very highly ranked initially, and am not sure if you are interested in submitting anything further, but I would welcome it.
