I'm now taking a drawing course at the Kummer art store ( www.ottokummer.at ), where the instructor is one Michaela Ghisetti, a professional artist.
First, I tried to paint with acrylics on paper, the sessions were about 25 minutes per pose. Most of this batch went in the can, but there were two I thought weren't as bad as the rest:
Both are about 70 x 60 cm, on glossy paper with a little surface texture. The paper is white, despite how it turns out here. The photos were made in late afternoon, on the shady side of the house, I guess that was a mistake.
