Here's some tips. I think of these sometimes when I'm painting, as I did just now.
Give a painting an airy feeling. It's easy. All it takes is a glaze. A glaze is any thin transparent color with lots of liquid, oil or water depending on whether you paint in oils or acrylics, applied with a large brush to all or part of the canvas depending on the effect you wish to achieve. It's amazing what a glaze will do for a painting. It's like looking through a colored lens. The glaze can cover up a lot of mistakes and turn them into real good stuff.
