feedback me on design 29301261 and 29301262 , thanks

I'd like this design to fill the rear of a T-Shirt. In the front a more simple design that could also be used as a business card logo. Many of you have great business card logos, but i'm looking for something more for advertising on a t-shirt.

thanks for your valuable feedback , let's check my revised design 29320535
and feedback me about it , thanks
