Madison Ave. was a great photo that really inspired me, so I decided to up the scale, and try it on a black background. Karin paints this way, and when Cheryl Andersonsaid that she had tried it, I decided to give it a go myself, and really liked the dark ground. I've been blocking in with thinner dark paint, and then using medium values, establishing forms and shapes. This way the blocking is done with the medium to dark tones...kind of saves a step. I have to say though, I like both methods. oil on masonite 12" x 16"
