I have just discovered the joys of the palette knife. This was partially because my local gallery owner was telling me that textured paintings are selling well at the moment. This painting was painted mainly with a the palette knife, I've been using the brush to give an airbrush like effect, mainly for mist.
I have created three painitngs like this one. One is going to Gallery-S (my usual gallery), one on Minigallery (FWIW) and one "spare"
