So I've gotten a bit farther on this piece today. I'm starting to put in the foam of the waves, but the shore itself and other items in the water haven't been added yet. I switched over from Inkpad to SketchClub to start work on one of the robots in the scene…
I really wanted something that had the look of a fancy mech or transformer. A more detailed, but obviously still mechanical, face. It'll get clearer what I'll be doing with this as I go on.
