This has been an interesting project because I used cold wax as my medium. I painted much of it before going on vacation, then added the foreground birds when I returned. Cold wax is very interesting to use and I am still experimenting with it. It has a soft look, and when painting over a layer that has dried it is very easy to wipe away any mistakes. Wax on, wax off.
It also makes a nice final varnish and you don't have to wait months to do it. It is not recommended for stretched canvas, though. A rigid support is necessary to prevent cracking.
I realize if you're not an artist this is about as interesting as reading the Tax Code.
