I do love how you handle the paint, and quiet often your paintings turn out great/beautiful! I am a fan for sure! BUT I want you to look at all of your ears....You paint most all of them as if the model is in profile....an ear will usually follow the jaw line angle-Not always but the ears never shows the foreshortening they need to convince me that the head is turning away from me the viewer.
I always learn so much when I see your drawings. I'm sure your work is a great source for many artists, for me it has been a great source for learning. Is there a possibility that you would upload the process of this portraits? ^^
