Composition: 2 - Straight on and centered, doesn't add anything to the photo.
Technical: 2 - Seems overexposed in the top right and is overall fairly over-sharpened.
Creativity: 2 - The setup could look nice, but it is really killed by the uninspiring composition.
Appeal: 2 - Taking into account everything I've said, and the fact that the placed shells don't really interest me, this photo lacks appeal for me.
Overall Calculated Average Score: 2
I've tried but I can't spot the odd one out! Hehe :)
