20x40cm oil on board.
I intended to do a paint sketch in one sitting of some of my favourite painters. This is the first one. But it ended up being more of a finished painting over many layers. Theres a few reasons for this: I forget how to paint every time I sit at the easel. My mind goes blank. I know to get a rough sketch in and add darks first but thats about it. My style is different every time. Sometimes the paint goes on nicely in the first layer. It depends though on what surface you use, which brand of paint, medium or not, level of priming, temperature, brushes, etc as to whether or not the paint sits nicely. Alors, not a sketch anymore but good practice nonetheless. Francis Hamel next (also in my top 3).
