Is this a Mongoose? If so, I never knew they had teeth like that.
His face is in shadow but the rocks to the right have light on them. The rocks draw the viewer's attention since they are the brightest area of the image. Using highlight/shadow and maybe levels more detail in the critter's face.
I like the shadows, but it would be better in my opinion if the darkest part of the shadow wasn't directly on his face. And yes I understand how difficult it can be to photograph wildlife. ;)
