Good job hiding that direct sunlight and creating a nice, backlit silhouette. The golden edges look cool as well.

Not much critique going on here but that's because the image is a bit small for us to be very critical.

I think the image is actually tilted to the right. The lens distortion hides this because the dog looks upright but the water appears to be sloping dramatically. Still works though because the dog is so strong and dominant in this one.

I think the dog is a bit too close to the right side of frame for my liking. I like a landscape shot might have worked better because you could have had the dog to one side as you've done here but leave more active/negative space to enhance the dogs interest in whatever is off to our left.

Welcome to ph.ca also.
