The only thing that would make this painting harder would be to add a lemon. You can see the influence of Qiang Huang in this one. If you like a challenge, try painting pewter, glass, brass and fruit in one painting, like this one.
The other day I painted one that was a "scraper." I don't often scrape a painting away, but the one yesterday deserved it. A large part of a still life painting is the actual setup, and I should have known the pot was too bright yellow and the spotlight too far away. The irises were beautiful, but they got scraped too. Darn yellow pot. Not every painting has a happy ending.
