Not being pleased with the last few drawings? Go ahead, turn the knob and see if you can work your way out of another box.

A figure in a bath, side lit from a window, cast shadows, reflected shadows, a tile enhanced perspective, all framed in a mirror on the wall.
Didn’t do too badly until I miss managed an alcohol/charcoal brush that was still carting a hidden dose of value. Lesson… try switching to a clean brush to move the last layer of value into place.
