I once did the following exercise in the Technical Course in Computer Graphics, using a graphics tablet.
I put a picture of myself on the graphics table and her pen went over it, making the contours of my face.

Here is the result of such work!

Self-portrait simulating different brushes

Although I already liked the first result, I decided to test the equipment more by making some more cartoonish drawings.

I also worked with another photo of myself:

Side self-portrait with various virtual brushes

And finally I made the following Art, composing with other graphic elements that I found interesting.
