They DO exist!!!

This was taken at Universal Studios Orlando, how is the composition?

The main thing that bothers me about it is the dinosaur's horn tends to be lost against the background of the rocks. The head completely in front of the green foliage would have made for a better shot.

 

Also, I think a little less empty space above the head would have helped.

Bah! That rock looks so fake!

 

IMO, the composition is pretty good, aside from the fact that the body of the critter and the water meet just out-of-frame.

The purpose of this type of shot is create the impression that you are looking at a living thing. The sudden cut off of the body leave no real visual evidence that the dinosaur is actually in the environoment, and not merely a rubber puppet being held up in front of a picture of the envirnomant.

I have tried to address the above comments in the attached photo, do the changes enhance or detract from the original?

The above update is better composition. Now, however, the manipulation is noticable around the horn.

The altered image is better. It'll never be a great shot, no matter what you do to it in photoshop, but the changes you've made definately help it.
