I could not stay away from my sketchpad. I have to admit, this took way longer than my alotted time, but it’s the weekend and it was fun!
The emphasis is on the musical ‘noise’ (not a big Hard rock fan) that comes out of the stage speakers. I started this one as a rough concept sketch in another sketchbook, got carried away and that one is let’s say version 0.9 of this one. I noticed that lots of erasing in a watercolor sketchpad is not really good for the texture, so I redrew my own drawing.
Here is the inked version, which I snapped to make sure that if this turned out to be a disaster, I would have a fall-back.
