Thank you @jamesartville ^^ But these are not done digitally, though I am now kind of proud to here you say that they look like it ^^ These are drawn by hand, hence the paper texture. I drew them with copic markers, crayons and ink. Though the originals are about 20x20cm each, so I shrank them a bit on the PC. Definitely will do a post about how the POLYGONS are made at some point!
