Riderless horse sketch

Its just a sketch, have a notion to do a piece on dressage, and I keep coming back to a sketch on a lunch break I doodled a month or two ago, which in turn prompted me to start on this. I was in half a mind just to add a rider, but didn't as the horses head would then be too far tucked in. Its a starting place for now, so I'll just see where this starts to go over the coming weeks....time for a bit of research, I think.

As ever if any of you have photos of you and your horses doing dressage that you would allow me to paint from, send a link.  I got a lovely great photo to work from Red Hot Ruby's blog a few months back, always on the hunt for something that sparks off an idea....
