My painting was finished last monday. I should add that the original photo by Koos Breukel was also very good. But still, it was quite a challenge to get it right. It took me 4 stages to paint this, with each a week in between (oils have to dry):
1: underpainting (below, left),
2: shadows, blues and the parts which should look like further away (below, top right)
3: light parts and the parts that shold come forward. (below bottom right)
4: finish and highlights (zee final painting above).
