3 acts - Blocking it in

So here's a glimpse of what I did last night.  This is the easy part (or the cartoonified underpainting part if you prefer). Now I can either make it a really nice painting or ruin it. If you don't see any more about this one then I guess you'll know what happened.
(it takes a while to get the actual painting going, and I'm not sure how much time I'll have over the next few days, so don't hold your breath)
