1. First of all, regardless of technique, this is an AMAZING picture. It's just beautiful to look at. 2. The fast shutter speed is spot on - shows every little details of the water. 3. The lighting is wonderful. It seem that the sun is low, on the far bottom right side of the picture, which adds a smooth light to the waves and a wonderful coloring to the skies. 4. The use of panorama here is brilliant. I think that adding further width to it would just ruin it. 5. I think that it's good that you didn't use a smaller aperture so that the back is a BIT out of focus. adds a bit of a painterly feeling to it. 6. I love that the contrast isn't too hard. It's calming.
