Why don't you post the reference picture right next to the finished on. This painting is just amazing. I thought it WAS the reference photo! How did you do black and white? I mean with what materials on what material. You know me, always interested in the technical aspects.
I'll have to post them together, you're right ;)
As for material, this one is done in acrylic on a canvas board. I was a little apprehensive when the lady said she wanted it painted in black and white but I have to admit it was one of the easiest i've done! Only 2 colors lol
