I began with the wood panel support, made of birch plywood of the best quality. I sanded and primed the panel 3, 4 times. Every time a new coat of primer was applied I carefully sanded it. To paint on those wood panels is a pleasure: the brush glides on the surface and allows very fine brush strokes, unlike canvas, which is a bit rougher. There are many different types of canvases, from portrait (very fine) to rough. There is cotton canvas, linen canvas, and even synthetic cloth canvas. Anyway, if the consideration of weigh when shipping a painting was not a problem I would always prefer painting on wood, because the brush just glides on the surface and very fine details come out superbly.
With this painting, I did not want details, however, rather I was looking for a contemporary impressionist look.
Please see the brush strokes in this detail view:
Also, my idea was to have the viewer focus on the figures rather than the background. I therefore kept all surrounding elements monochrome and used colors only on the figures and bench. I also believe in "key notes" in my artwork. These "key notes" are usually two colors contrasting and one color being the "key". It is more or less what is called a split complementary color scheme as shown below:
