My mother in law grows these wonderful orchids that are in bloom now and lasts for weeks as cut flowers. She cuts some for me every year and I thought I'd paint them expressively as practice. So that the brush strokes are clear, I magnified the orchids and cropped the composition.
I textured the background ala Vincent and indicated the leaves. Resisted as best as I could the impulse to smoothen and blend colours on the petals. It's rather therapeutic to paint still life. They don't move and if you put an artificial light source on, it doesn't suffer the problems of landscape either.
