Using a shaving mirror to view my reflection for the self-portrait element of my painting meant getting in very close to the subject, resulting in a close-cropped composition, which I think makes quite a dynamic image. I experimented with the composition through a series of small vignettes before settling on the final choice with a larger pencil rough drawn to scale.
My usual practice is to work up the final image by eye, rather than use a scaled grid, drawing in the basic elements with thinned oil paint over a tinted surface, in this case plywood prepared with primer and gesso.
