I hate to say it but this is difficult. This is because you have to know it inside yourself and have confidence that the marks you make with white, yellow or even darks are truly going to sculpt the image and make it look alive! Then, you must do it again, but you have the pattern in front of you. If worse comes to worse, you can wipe it all off and start over tomorrow. I tell my students, ‘if it doesn’t look right, it is just not finished!’ This looks better, hopefully, on the next pass, it will be finished. Well, I still have the hair and the shirt. It will be interesting because the light in the shadows is a glowing cerulean blue. That will be a challenge. This is the part that I need to show my students.
Enjoy your painting. Shalom, Diana
