Originally I went straight to canvas on this, but realised that there was a lot of investigation of shapes and tonal relationships, so stopped and went back to the drawing board (literally!), and spent some time drawing. In truth, if I miss this step I am always sorry. While colour is the big attraction, it is much harder to get everything right when you don't prepare.
The word 'drawing' doesn't refer to the medium - we can draw in anything, including paint. But if we take it to mean 'investigating', 'studying', 'problem solving' and 'gathering information', it is a much larger task to do all of these things on the canvas. After the drawing I did a colour studt, then returned to my canvas. I painted many layers, and managed not to be precious by painting over the whole face four times, to see what would happern. Lots 'happened'!
