Hey, I'll put these up for folks to (hopefully) enjoy: You'll notice that one is very similar to the cover of the book in my sig line - that's because it's the upgrade to it. The book, which was never intended as a commercial project, simply a test bed / hobby, has actually sold a little despite my utter lack of marketing and general neglect, so I'm updating the cover - the finished version should be brighter, perhaps a bit more like the filtered version.
The second is also a bit of cover art for the project I'm creeping nearer to the end of ('Questions authors ask about... Space Disasters' is the clumsy working title) - it's a lot less far along but you can start to see the general plan.
