T-shirt/illustration ideas

So I've had a couple commissions to do designs for t-shirts (I have a couple of my pokemon shirts for sale here http://www.printfection.com/circuitbreakmerch/Mens-wear/_s_514764 ;) ). That piqued my interest into doing designs for shirts, accessories and what not.  Keep in mind, these are purely conceptual at the moment and if anyone were to want a design like that, just message me.

(this is Hello Kitty's anatomy, I'll clean it up and post it soon)
