After a battle with my tablet, I doodled this in Paint.net xD
Watermark because this isn't a free line art, and I figured that with all of the crazy fill-tool users out there, a majority of them wouldn't read the description anyway. owo
I mean, if you really want to use it (it's pre-shaded, so fill tool and minor pokes with the most basic of brush tools will work well if you just use varying shades of the color(s) you need), I don't think a few points to show support for the artist (and in hopes that you will actually credit me xD) is much to ask. owo
