Sketching mixer desk and deejay. The first one has a terribly disproportionate head.

Line drawing.

First color test. I've no idea how to aproach it.

Second color test. I'm trying with a color palette that I like for the figure.

Adding some shadows and atmosphere.

The final illustration.

Black and white help me in the last step to adjust contrast.

Zoom in.
