This was colored on a cheap Windows 10 tablet using a capacitive stylus. It was no wacom, but the stylus worked surprisingly well. The main drawback was that due to a quirk in Photoshop, I had to keep the image zoomed-out while shading this, which limited how much detail I could put into it. But that's hardly an issue when the picture will get shrunken down for the game anyway. Unfortunately the tablet was cheap in more ways than one and broke after only a month. But I still managed to color a few pokemon on it.
