There's really nothing there, no robots, no spaceships, no aliens, there's just some dust, some light and some visible energy. Between you and me, I was just playing around in Photoshop and got lucky. I like the sense of depth, I like the contrast and the colours. I thought about compositing some rocks in, but its nice as it is. I tried animating it, which was interesting. I've been using Photoshop a long time and I'd like to get into matte painting. For me personally, this seemed like a step in the right direction.
