This is a good exposure and composition with the placement of the animal and the sun.
The only issue is we can't tell what kind of animal it is. When shooting a silhouette shoot it so that you can tell what the animal is without a text explanation. The photo must stand on its own and tell the story. In this case, it is just a fuzzy fur outline.
Stefan,
I fully agree with Steve. I hadn't commented on this image as I had wanted to think about it. I can't make out that the animal in the image is a baboon or something else. Exposure is right though. I find the wavy bottom of the Sun funny. It appears as if the baboon has chewed it. :-)
Some of our abstract images work and some don't come out so well. That should not stop us from experimenting. Please keep on sharing.
