Entries #13 and #12 - Thanks for you entries! We think you are trying to do a spine, however, the curvature is wrong/opposite. The font is to "scientific", in my opinion. My husband likes the sunlight aspect. The tag line should be after the name of the business, not on top of the logo. The green is off; looks like pea soup. We would like to see the brain and the spinal cord represented somehow. We look forward to seeing your revisions. Thanks!
