This is a first for me. Oil, that is. It might be a last - talk about a high-maintenance medium.
This guy is sad because he is aware of his likely future of loneliness. I'm pretty much a watercolor or gouache painter. Occasionally acrylic. And you know what they say, oil and water don't mix. Or was it oil and vinegar? Wait, no, that's a salad dressing. My favorite kind, mind you. When I eat salads at all. But I digress.
Someday I'll do oils again. But I might need guidance. Like a class or something. Imagine that - actually learning about something before you try it. Do people actually do that?
