Especially in the hair, I think. Yeah, unfortunately, Leyendecker is much overlooked; he wasn't a very public figure whereas Rockwell, who greatly admired him and emulated him, is much more known. It's a real shame. His style is incredible.
I'm reminded of a sculpture. The angular way you captured his hair and facial features is very interesting! I also like the way that the light values are captured, with the lips being very light and hair curls and eyes being darker.
