Recently a friend of mine mentioned he was putting together a tech/gameplay demo reel of a game he's been working on, and I offered to provide some placeholder graphics.

After some quick fiddling around, I settled on a monochromatic cartoony space feel.

This is a copy of my test area in Inkscape where I put the elements I've made together to gauge how they look together rather than an in-game shot. (I might see if I can wrangle one of those later).

If you're interested, I've written a short blog post about making this.
