Update

This is an object (also abject) lesson in patience a.k.a. not adding a layer of paint until the one beneath it has dried properly so that it doesn't pick up the pigments and screw up the the transparency and tonality of the new layer. Oops.

A rescue mission was launched.

Also have to really make sure that the back toes of the back foot curve away from the edge of the canvas so as to avoid the creation of impression that the composition is jammed into the right edge.
