Okaeki VS Sketchbook Express
I find Sketchbook much easier to use, because you can zoom in with your fingers, and the layout is a lot tidier to me. I have nothing against ChickenPaint, but BOI, it's hard to use.
I drew Undyne, from Undertale. Boy, oh boy, I need to go learn how to draw humans and humanoid creatures. But guess this is alright. It's just a sketch, anyways.
