I spent today cleaning up and refining more details and the overall values. The overall value structure of a painting is really important and I always try to balance the lights, mid-tones and darks. The best tip I have for balancing value is to squint a lot while you paint. Squinting helps to keep the values accurate.
I should be able to finish this painting in the next session and then let it dry before I sign it and varnish it!
