That's great mate! Look forward to the updates, it'll be worth spending a full night on it as it's coming along really well.
Agree with the crits too - yep that cup does look translucent (as does the squirrel's foot). Not sure about "rim bubbles"?!
*examines his morning coffee* Ah ok... yes now I see them! hehe (you may want to but a bright specular reflection just on the inner edge of the coffee around almost the entire circumference (wow... amazing what you find in a coffee cup...)
I'd like to see some more highlights on that fur too. (which look kinda gold on a red squirrel)
Oh and a brief explanation of your 'squirrely past' would be good (not sure I want to know... but I'm curious

)
