This was just a portion of a mural I designed for an Advocate Educational facility in Los Angeles. The mural involved a female teacher instructing an adolescent in computer advancement. The woman's posture was important to me as well as her hands and personage. This sketch was instrumental in the assembling and final execution of this piece, it completely facilitated in working out the schematics, scale and glitches prior to actually painting the final wall visual. I decided not to use a grid pattern on this but rather, visually transfer the sketch, planning the lighting techniques freely to fit the rest of the mural. H Rios
