They say that sunset or sunrises are more beautiful with pollutants in the air. Just hitting on that. Who are "they"? I'm not sure just heard it somewhere. Thinking on black, maroon, or army green. Thought gradient or simulated process would look good. 4 - 5 colors depending on shirt color. Also, with or without grass on bottom of design.
I love the closeup. It definitely looks better when the shirt color is the exact same shade of black as the image. The smoke could be a little smokier where it originated.
I like it except i think the smoke stacks should look more real like the tree does instead of a cartoon shadow. If you've got some time please tell me what you think man. http://www.threadless.com/critique/42082/Ant_Wars#v2
