My first two efforts to create a decent John Carter drawing fell remarkably short of the mark. Clunky compositions, weak black spotting, questionable anatomy, the whole nine yards.

I'm not completely happy with the perspective on the city in the distance, so I will be tweaking that before going to the inking phase.
When the inks are done I will post them before going to color.
