With some time today for working on this image, I set to add some new elements to the picture and refine others. Now the Jeep, which I colour-corrected, is being held by massive robotic pincers. The giant robot has a few more details, but some items like the missile launchers are just blocked in. Noteworthy is how I used Photoshop's excellent Puppet Warp to break apart the Eiffel Tower in a pleasing way. One or two more passes to add stuff and make fixes, and I should be done.
