I haven't yet decided how illusionistic I want the bricks to be for the current work, only that I don't want it to be 'clever' as in Escher's wonderful works; so there will be a bit more sketchbook work (sans dinner, hopefully) until I make up my mind. The decorative, flat mosaic style may be more appropriate for the drawing I'm working at the moment, but I may do something different in the next one.
