Hi! I'm critiquing this for the Feedback Frenzy event.
First off, I adore the bright colors you captured in the sunset and the reflection of the sun in the water. It makes me long for walks along the beach and inner tubing and evening boat rides on a lake The bird is a nice touch, and I have to say kudos to you for catching it in flight and not in the least bit blurry or horribly cut out of the frame. I've tried taking pictures of birds in flight before with little success, so I know how hard it can be. You did a great job.
Just a couple things I would suggest for this picture as far as technique. The picture could be straightened just slightly so that the horizon isn't quite so tilted to the right. Also, it bugs me a little that the bird's right wing is touching the edge of the picture. There might be a little too much negative space on the left side of the picture and not enough to the right of the bird. In the future, I would suggest that you try positioning the shot so that the sun is more to the left of the picture instead of the center.
As far as creativity goes, sunset pictures aren't super original, but I had to mark you up higher because of the bird. I'm not sure whether it was luck or opportunity that allowed you to capture it so well in this shot, but like I said earlier, it's a nice touch. The bird sets this particular shot apart from other sunset pictures.
I don't see anything that needs critiqued as far as quality goes. The picture is sharp, and the clouds, trees, and waves are clearly visible. It's not grainy or blurry.
Overall, it's a very good shot. Keep up the good work!
