I would like to see entry 6 in a perfect circle. The two C's are protruding out of the circle. I would also like to see the logo in different colour variances of the grey, blue and green. I would also like to see entry 16 in a circle.
81 looks good but the edge of the C on the left and right hand side of the circle need to come in a little bit to fit just inside the circle (No blue colour on the edge of the C's).
