Non-Compliant Abalone Shell Clock

I'm curious why this image was rejected for being NON-COMPLIANT. I thought it might have been my key wording, so I resubmitted with a minimum of specific words. Again the image received a NON-COMPLAINT rejection. The clock is not a commercial product, but a home craft assembly. So what am I missing?
