These photos show a small landscape (approx. 12" x 18" painted on an oak trunk. Painting on oak is not something I recommend as the grain will swell with the moisture of the paint, even if sanded between painting sessions. This trunk was stained and sealed prior to painting, and still the grain shows... Not a huge problem, but I'd never choose oak for a detailed piece or for portraits!
Moose are fun to paint.!
