The darker color and shading look great. I think I like the character in #31 and #34 best. I'm having a hard time deciding if I like the graphic-on-top version (which I wasn't planning on, but really works here) or the graphic-on-the-left version. The downside with the left is that it makes the logo both tall and wide - but I like the reflection, so I don't think it can be moved to the same baseline as the tagline without it looking odd. I'll play with these and see if I can work up a layout that uses this space.
