As always, I started with the eye and then moved onto the shadows and mane but not so sure about his eye yet.
Mostly 2B with a little 4B (for the eye and shadows). Definitely a challenge to make this look like a white horse. I think the "key" is CONTRAST but that's just a guess LOL.
A lot more work will go into this before he is finished.
Hope you like it so far!
