Sketches - Centaur Market Scene

I finally decided to start working out some ideas for another centaur painting, this one with a market/bazaar theme.  These intial sketches will be very rough, without details until I settle on the layout to paint.  Once I have my plan, I'll work it up into a more detailed and exact drawing, but, for now, this is as much detail as it needs.  This is about a 10x14" vine charcoal sketch.  More to come as I work out varying ideas on this same theme.  Any comments or suggestions welcome here!
