I assume the green, blue, and pink on the CPO align with the bezel.
How would the CPO look with a black (or dark woodgrain like your barrel?) background and subtle white outlines around the barrels and character instead of the green, blue, and pink?
Do you want DK on the bezel
and both CPOs?
Consider keeping DK on the bezel, moving Mario/Jumpman to one CPO, and putting Pauline on the other.
