very nice work so far.
Maybe lighten up the left edge of the hat. Give's more depth. Toning down the light spot on the left, because it is laying deeper and therefore getting less light. I should paint a less lighter spot from top to bottom darker all the way from this spot.
But it's only my thoughts.
Thanks Marc. I know there's more work to be done on the hat and I think your thoughts on it will help. I need to put it aside for a day or so and take a fresh look again later, it's making me at the moment.
