Mmm. It doesn't look like much. I painted this from a photo I took in Airfield a while back. The exercise was to do with using just one colour, Green Apatite Genuine. I did manage to create lights and darks. But it's a bit ... monochromatic. I must try something similar with Ultramarine and Green Apatite Genuine - I think that would be a bit more exciting.
Anne-Laure Jacquart, the artist who inspired this, managed to make a much more interesting painting out of the one colour! Check out her video below.
