New Digital work from sketch

Recent sketch I drew. (steps to digital rework)

First did a sketch on notebook paper.

Then scanned and cleaned up image. Then used a blur filter on it.

Next gave it a greenish tone and retrieved the outline with an edge filter.

Lastly, I used a Coherence-Enhancing Filter to get the curved flowing lines.

Here is another caricature I did from a sketch pretty much the same way.
