I got some dried out ugly as balls shade of sepia ink at the art store (I didn't know it was dried out and I can't return it) and it's ~$8 for a tiny (30 ml) bottle so I have to find something to do with it all. I found out I can do this with it lol.
I did an under-painting with the sepia ink and then I went over it lightly with watercolours using my handy-dandy water brush.
I'm most definitely going to do something like this again. Maybe a robot.
Maybe a steampunk robot.

This is an ATC for  seve89 of Giovanni, a hammer head shark anthro thing (??)
It's about 2x3 inches.
