I'm a concept artist specializing in vehicle design. I design the units and vehicles for the upcoming game Aero Empire, and I regularly submit concepts to the indie project Infinity: The Quest for Earth...
A heavily armored destroyer designed for Infinity:TQFE. This is perhaps my favorite out of all the spacecraft I've designed. It was based on H.R. Giger's Alien, and is essentially a mechanized version of the original creature. If you look closely you can pick out various anatomical structures including the eyes (yes the Alien actually had them), mouth, teeth, jawline, and the xenomorph's trademark elongated cranium. It's not drawn, but there is also a telescoping docking arm right where the alien's retractable mouth would be :)
