Used a number of photos as a base for this one, namely random models of AT-AT/STs from hobbyist/stock sites. They are all heavily modified of course. I've also added some details that I often add to AT-ST's that I paint- commander's cupola with blaster mount, searchlights, shielded weapons, bolt-on skirting to protect the batteries at the rear.
For the art direction in this image, I was really inspired by the cinematography at the end of "The Mist". It feels somewhat majestic and dreamy, but also coupled with tension, knowing that horror and chaos is not far away.
Done for Sony Online Entertainment's Star Wars Galaxies Trading Card Game.
