Finally getting somewhere with the horses. I went back to more of a contour-like original drawing which gave everything a bit of life. I don't know whether this is the final thing yet but we're close.
Some intermediates :
The drawing. Looks a lot better at this stage - I need to remember not to get too stiff in the painting.
I did the horses and riders one by one. First the central figure. The faces are so small it was impossible to get a likeness. This may be a good reason to do a larger version.
Second horse in. I'm feeling pretty good here. Thankfully I didn't screw up on the third one.
