Chimpanzee - Digital Drawing

Hi all!

Here is my new digital art. It's a sketch of a wildlife creature known as chimpanzee. The dude doesn't seems to be in a good or angry either. He's just focusing his sight at a particular spot and having something huge on his mind.

The piece was done with AutoDesk sketchbook application using a combination of scribble and hatching style . My steps can be seen below:

Thank you.
