Tom,
Two comments:
1. "Bitchin!" I had to warp back to the 70's for that comment.
2. Have you played with it? I would think some Shadow/Highlight (very subtle) would work here nicely to amplify on your fantastic work. You grab a break here, as any noise you produce will be dark enough to be pretty invisible. Splendid capture. Post some more of this great stuff.
Spectacular ! Great work on the clouds. I like the way they are emphasized, either by the light blue tone of the sky or by the intense orange near the coastline. Nice job on the foreground too, there's plenty of detail available, even though the scene is quite dark. The S-shaped light reflection where the waves receded adds a beautiful touch.
