The Empty Ocean

I'd love to get some constructive criticism on this (ratings are good

too, but words are better). I took this long exposure on the balcony

of a cruise ship on my vacation to Hawaii. It's around 9pm or so and

is pitch black -- leaving the shutter open for so long makes it look

more like dusk. Overall, I really like this picture but am looking

for feedback on how I could've made it better.

Thanks for looking!
