Just Krita with some default pixel brushes! As for the canvas it's about double the size as it originally was because i nearest neighbored it to be bigger. Surprisingly you can double the size of a pixel drawing in Krita without too much fuss so long as you make sure its exactly double. Although sometimes if you do it after using dithering it can look a bit odd, but its not too big of an issue.
Just an old pic of more pixel-brush using Krita art, nothing new.
