I've not done a lot of creature modelling so I thought I'd have a practice with this guy. I modelled the base shape in my homegrown app (Clayworks: https://plus.google.com/105770187318983146114
), did the detailed sculpt in Sculptris and then finally brought it in to Blender for re-meshing, material setup and skinning & rigging. The hardest bit so far has been the skinning and rigging: bits of mesh want to poke out all over the place. It's a work in progress, C & C welcome.
