I was amazed by this picture. First of all it's really 'clean' one. Every object which appears on this picture is exactly where it should be.
But real strength of this picture it's colors (which blends well from blue to yellow) and symmetry of this picture. Thanks to that it's not overwhelming I can feel almost that peaceful dawn but the photo aren't getting boring.
I really like the boat in left corner. It makes it a bit more lively as someone just left it few seconds ago.
It's surprising how colors are dividing picture into 'parts' but it's not disturbing in any way when you're watching at picture.
