Got some sketches. Practicing with character likenesses. I find Luke's likeness a bit easier to nail down than Han's, though I still need to iron out all the kinks.
Luke didn't turn out too bad. Some issues with the mouth and jawline, but I'll hammer those out in other images.
Han turned out awful. The only thing that's good about this image is the linework. I referenced from a tiny Indiana Jones image and three photos of Han. It still fell flat.
This one turned out a bit better. Referenced from an Adam Hughes rendition and two photos of Han. His trollface amuses me. He still needs considerable work before he gets to a point where I'll be satisfied.
