Here's an update to The Harp of Pete Castiglione where I shaded his back a bit and add more realistic detail to his fingers. When I first outlined his back, I used a thick-tipped marker to outline the back way too thick. So I used special metallic crayons to try to correct the problem. Here's the result.
UPDATE #2: Added more blending of color to Pete's body to blend in with the colors he has. I admit I'm not good at shading, so this is the best I can do.
