I like #23, #54 and #59 the best so far, but I'm still not totally sold but not sure why. I think #23 is a good concept, but it seems a little bland.. #54 is too masculine, but I like the concept, and #59 I don't like powder blue because it doesn't seem quite as professional. Also, could you duplicate these concepts with a different font, perhaps from the design i have ranked first so far? #56 and #56, there is just too much to it, i don't want the logo to overwhelm the design
