Nice handling of exposure with the harsh light. Whites are good, with some detail still showing in the blacks.
Agree with Todd about the bill, would do a mask and lower the saturation there, while leaving the blues alone.
I agree with Leo about more space, a bit cramped all the way around for me, but esp. to the front. Not much, just a sliver would help.
Great pose and background. Nice handling of the whites. Maybe its just me, but I find the out of focus shells/pebbles right at the bottom of the frame a bit distracting.
