I'm still undecided which ones to buy! I hope you have some input to share with me, and maybe even a few other fantastic recommendations as well? :)
These I found via Society6. By Edward J. Moran II and Budi Satria Kwan
These two are from WhatWeDoDK on Etsy
These two digital watercolor prints are from Vivideditions
This Japanese print is from PrintablePixel. I've tried to tack down the katakana print, unsuccessfully, but the photo was taken by Hideaki Hamada.
