Comicon 2011 - Concept shape sheet

I've been sketching in my sketch book today, something I've not actually done in a long time, continuing my entry for the Comicon Challenge 2011. Here's a couple of sketches I did.

From here I started drawing up my concepts in Photoshop. This image shows my progress in the two thumbnails at the side and then where I'm at now

Concept modelling tomorrow, watch this space...
