Chimpanzee In Thought - Digital Art

Hi all, greetings!
Here is my new digital art. It's really been a while I drew a chimpanzee. They are among my favorite animals that I love to draw. Yeah, they are always fun to draw - especially those their expressions and fur.

Here, I drew a young chimpanzee in though. One if his fingers rests on his mouth with his mouth affixed at a particular spot. At this point, his mind must have gone far away from there.

The piece was done with an AutoDesk sketchbook application and aided with an S-pen. You can see my steps below:

Thank you.
