Which art would you like to see on a playmat? (Patreon)

Hey everybody, while the present is a bleak wasteland in which I'm still trying to ship things in a pandemic, in the bright shining future there might be the glorious day on which I actually print playmats for the first time ever. 

If that day comes, which art of mine would you really like to see on a mat? Just tentatively asking as this is still a bit down the road, but I'd love to hear your feedback!
