I like ur cat 🐱
First 4 are fine, Id swap 5 and 6, swap 7 and 8, leave 9 and 10, swap 11 and 12, and brown goes before red instead of with the grayscale
Purple should be at the end, red at the other end
The light green should be before the dark green
Light green before dark green, pink before red, white should be on the opposite side of the spread from black (white should be the farthest left)
The pet is cute too
