#3, The typography in most of the designs posted are bad ( though the initial idea may be good ), while #3 isn't idea here are my suggestions to improve it:
1. There is no symmetry between the slogan and the logo box, find some way to fix it.
2. The text in the box itself needs to be correct, by spacing the fonts on the bottom word for example.
General Comments:
I don't like the font the designer chose, the company brand feels corporate so it should have a serious font. Mixing typefaces as in the second example is always a bad idea. I feel that the company itself can be easily branded simple because it has an emotive word in the name ( Pink ). Best of luck with your design.
