These are very interesting! I like the flower in #13 because of different colors, I don't think it should have only one color like #14. Colors in #13 are nice...however, I think the color palette should be a little more "pastel" like and toned down. This is nice but it is a little too vibrant. I want people to think "relaxing" when looking at the logo.
Also, do you have any other flower designs? This one is okay, but a little too abstract.
