This image is the one that I believe is the best. In this photo we have high contrast, with the light hitting the stuffed animal towards the right side of this picture. There are hardly any middle grays. I would also describe this photo as low key because of the dark tones seen. The feeling I get from this photo is of desperation and even sadness because of the lighting featured in this photo.
this is a good example of a low key photo. the tight composition also adds to the mood. The animal feels trapped. though the teeth are somewhat comical.
