I think the design on top could be a cool character. Could you try something with a full body to the left of the name? In regard to the words underneath, thanks for trying to incorporate those but they are only placeholders for now so I'd be unlikely to put them in a final design.
I came up with another little caracter, A multi tasking character that helps you to get you fit
that why i made his antenna put the DOT in FIT..he helps you out.....it can be part of a very interesting advertising campaign!
If you think it has potential, let me know, if not let me know tree things you character you would like it to project!...I think you need a character, to SHOW ITS THE ZOOKOF FITNESS ..a multi tasking octopuss
