They say you should paint what you know. In the case of the little filly, there were issues. I asked a horse friend to look and see what was wrong with the painting. He was kind enough to be blunt. She looks like she has a cows nose and little baby horses are like children, their features are nothing like an adult horse. The fact that I know cows, but not horses is evident.
Back to the drawing board and the palette.
This one is much more representative of young filly. It was painted over so the strokes are not as painterly as I would like. But an improvement and another lesson, not just art but life.
