Wow! As someone who grew up on the beach, I'm a sucker for beach + sunrise/set shots. I love this!
The exposure is perfect IMO, because the sky isn't washed out at all like the sun loves to do.
If you don't mind sharing, what did you do to the picture PP? Was it a multiple-exposure shot combine in PS? What camera/lens/etc? The EXIF data isn't there :\
