Here's my latest effort at still-life, 6"x8" Oil. Painting glass with liquid in is a joy; the subtle colours and reflections and distorted bends of the flower stalks was an enjoyable tussle. No secret to it, just paint what you see, not what you think you see - that's real-life painting in a nutshell.
I've tried painting these still-lifes a little looser than I normally do with my landscapes, but it's tough to change the habits of a lifetime! Regardless of how loose you paint, the drawing of objects, especially round ones, must be accurate - if the ellipses are wrong, the whole painting collapses and just doesn't read right.
