Spaceship Doodles 1

For those that have worked with me, or studied with me, I tend to doodle sci-fi things. In school it was all robots. But for the last few years it's been pretty much all spaceships. Always quick, always rough, never coloured or finished, they've never been much more than idle practice and a pleasant distraction. But I thought I would post a few that don't look terrible and to which I'm not especially attached. Each image is about a page in my sketchbook, and takes . . . 10-12 minutes at a guess? Usually the ships are every which way but I took a few minutes and orientated them in a less slip-shod fashion.
