"Ready to Compete" stage 1

"Ready to Compete" oil on 36"x 24" canvas

Here is a challenge for me, 7 horses with riders all getting ready to compete, and on a 24" x 36" canvas!
This is the drawing layout, that in itself too ages, but now I'm ready to start painting in the tonal values in thin Burnt Sienna.
It's a complex composition I only hope it works, time & patience will tell!
The reference photo is one I took last September at the Caledon Equestrian park.
Wish me luck!
John
