Wonderful profile Ray with terrific detail and good looking color. I'm impressed with the IQ using the 2x TC, very nice.
I like this one a lot. Only suggestion is that I'd be tempted to clone out the small catchlight (reflection off the water?) near the center of the eye.
Very well done.
Terrific portrait with lots of beautiful details. You did well to stop down from this close distance to get more within dof. If mine I'd be tempted to slightly tone down the brightest stripe on the neck, just to reduce its tendency to pull the eye. Really well done.
