Horse Fleming

Can we say I like a challenge?  I believe we can LOL!
My next painting is a challenging pose to try and capture in a painting.  Contrary to popular belief, this is not a smiling horse or a laughing horse, it is called "fleming:.  The horse does this when they are trying to get a better "taste" of the scent that has caught their fancy.
Here is my preliminary sketchings with the grid and without.
I'm just about ready to transfer it to my working paper.
