I agree with your wish for more DOF. NIce pose for sure and good capture. I wonder why you went for ISO 200 and not 800 or so. Not that I use a Nikon but those folks, whom I know use them, rave about great high ISO performance. Your DOF wish could have been realized.
Nice pose and profile of the head. Smoky skies not ideal:(. I think it may be worth trying a reversed S-curve to lighten the darks and thus bring some detail into the wing and eye while darkening/maintaining the smoky sky tone and leaving the highlights unaltered.
