I love the use of the cross into the 'O' , nice work! I really like that gray color used in the design I ranked #2, so I'd like to see 'at core health' in gray. I would also like to see the 'O' cross in that green color you used in entry #36.
The EKG underline is cool but I'm not sure it embodies what I'm trying to portray with the company. I need something a little more soothing- I wish I could come up with an example for you but I'm drawing a blank as to what that might look like.
Keep it up, thank you!
