About the design:
I went with a mostly naturalistic design using the base colors provided, and I kept some aspects of her old design while adding new elements. I did go a little bit overboard on the spots in the top and bottom views, so the side view shows a simplified version. The design is symmetrical. I made her ears dark grey with the lighter spots because I read somewhere that wild/big cats' ears and tails maybe have the dark tips for contrast to make those parts easier to see for body language reasons.
I hope you like it!
