Latest version, with an improved animation:

(Wait for it, it blinks... eventually... wait for it... now!)
Took one colour out and put another one back in for smoother shading, added wrinkels around the eyes and mouth, fixed first bend after the loop on the ribbon, etc.
Don't want to go overboard on the animation, as i think avatars should not move too much since they can destract from the actual posts
I also don't want to drag on a thread with 'i added a pixel here and there', so this is it... i'm reasonably happy with it... on to a more elaborate animation next, i think
Thanks for all your help, appreciated
