draw a cute T-REX icon/mascot

tinyRx

We are a prescription delivery service.

We'd like a Tiny Rex designed. Basically, a small cute T-Rex. He would need to be simple enough to work as an icon, but flexible enough to be showing doing things - riding a bicycle on delivery, wearing a headset for customer support. He also should work as a line drawing and in color.

The ones below are appropriate cuteness, but I'd like something with a little more line emphasis (color can come later). I do really like the exaggerated anatomy of the stegosaurus.
