Pitch project getting started on t-rex

This is what i have come out with in my t-rex designs.

what i'm trying to achieve in this character is to make the head bigger then the rest of the body, caricature the t-rex, maybe using small eyes or really big ones.

The first image on the bottom page i rather like but it look a bit to mean, the proportions i wanted looks right, maybe develop that character maybe using different eyes and expression.

My other favorite is the picture at the end the dinosaur at the top, the head looks noticeably bigger then the body.

In the coming days i'm going to develop my favorite designs and hopefully find something that look good.
