Yes, but I have a nagging feeling about them. I should have put the saucer-shaped 'head' section the other way around. Then that protuberance on the top could have been painted up like an eye (or scanner). It was a big mistake, and still nags at the back of my mind, years later.
But I honestly can't be bothered to go back and redo them, so I ought to just let it lie, really.
