Have to be honest - Love your thinking out of the box with the "Perfect 10". Possibly a colour variation and one on a black background? I love the simplicity
I was short of time this morning and just wanted to get the concept out there before I had to log off. I'll polish the image up, spend some time on the text and provide some colour variations within the next 24 hours. Please let me know if any other ideas come to mind in the meantime.
