Solar Krab
Inspired by Blacktron, this asymmetrical spacecraft is supposed to look quite alien. It has a unique shape, so as to fit in with the other Blacktron vehicles, and it has numerous small details, like adjustable flaps, a remotely rotating heavy gun, and various scanners and sensors. In general, I always liked the contrast between the cheerful smiley faces of the Blacktron space men and their dangerous weaponry, so I made sure to illustrate that in the last picture.
