Here's some art I did for a personal side project recently, sorry I didn't put it up sooner:
It's some kind of alien energy amplifier installation that's piggybacked on a hydroelectric dam in the American Southwest. They're stealing our power to build a hyperspace bypass! At right is our human stealth soldier who's trying to infiltrate the plant and destroy it.
Here's the initial set of value thumbnails:
Then I did a larger value pass:
And then a fairly tight line drawing over that:
From there I combined the line art and value pass and painted it. It's kind of a rough paint, about halfway between a speed paint and a polished image.
Also, I did a some more detailed drawings of one of the big weird machines, first a couple of orthographic views:
Then a 3/4 view lineart and color:
This wasn't an assignment for the environment class, but it was kind of related to it. I don't think it counts as homework, because it's not in the theme of the class... oh well. :)
