Very pretty. I've never seen a sunrise over water in person before, only sunset. I don't usually like the object being centered in a picture, but it works here. And I like the complimentary warm and cool colors. Good work!
"The artist is a receptacle for emotions that come from all over the place; from the sky, from the earth, from a scrap of paper, from a passing shape, from a spider’s web." Pablo Picasso
Often times sunrise/set pictures fail to stand out because they lack a foreground. You did well to put the rocks there to set this one apart from the rest. However i don't agree with the above comment that the sun in the centre works here. I think it would be better if it fell on one of the thirds. Overall a good shot however.
