Hi Cheryl, long time no speak.
This is really gorgeous, love the colours, but more the body posture. Quickly looking at the image, I would look to adding a Curves mid tone adjustment, perhaps two with various degrees of masking just to pull out a bit more shadow/depth fro the whites and add more form within the bill, avoiding the blacks of the head. Whether you add to the BKG is option, I have. You can
perhaps get the same effect through adding a Contrast adjustment layer, however to do this the
'proper way' is more complex with a combination of Channels, Curves & Levels in one go as an adjustment layer, plus an inverted version with masking.
Hope it helps.
Steve
