Something a little more than a sketch but not what I would consider a full painting... eh, we'll call it a sketch.

Scanned in a ballpoint pen scribble of my cheetah character to practice some digital brushwork techniques on it. I tend to get too focused on using a very small brush for everything and that's a bad habit to have- so mostly limited myself to using only a large brush size for this one and focused on carving shapes with it.
