I admire your dedication, getting up early and naturally having the camera with you...
Particularly enjoyed the second and third, #2 for the setting up of the shot with the surfer/swimmer in the background. Tempted to crop a smidge off the bottom and the right to make the surfboard more prominent, maybe? Just rambling...
Wow, the third one just grabs my eye with the lines and away I go... Maybe drop the really bright highlights off the top of the sky though so they dont drag the eye to the top maybe?
Hmmm, wonder why I'm in cropping mood at the moment
Oh, and I can understand what you mean by visiting places when other people aren't there, working IT nerd hours means I work a combination of day-shift and night-shifts, gets confusing sometimes but it works out others too huh...
