Nice sky and colour treatment. Would love the boat to stand out slightly more but perhaps you've been stifled by the basic editing rules. Creates a sense of drama nonetheless.
I've been on that boat!
I have questions for you to ponder, what is your subject for this photo?
If it was the ship, did you capture it correctly and make it
look the best it could be?
Was your subject the clouds, did you apply neg. space?
Do you see were I'm going with this ?
