I have tons of his rough sketches and caricatures and thought I would attempt cleaning one up in illustrator.
It's very tricky trying to pick just the right lines to make thick and thin. I try to make every line mean something, not just float around inside the silhouette of the forms.
So for each line I ink, I look for the other corresponding line that describes a form between them.
It ain't perfect but it's fun to do. I think I lost some of the triangular shape of Duke's head.
If anyone is interested in practicing their clean ups, I could put more of Jim's drawings up.
We are doing a job together now and maybe we could use another clean up artist for him.
Let me know if you wanna buy any of his art too, because he has some for sale. It's genius.
