Sprites
I fear my sprites may be a bit too, um, "distinctive" to be useful to anybody, but even so maybe somebody will be helped by them. I stored everything on separate layers, so it should be easy for intermediate artists to try different hairstyles, change colours, shift features around and so forth. Same for individual eyebrows, lashes, eyeballs, mouths etc - they're all separate so you can mix and match them for a ton of expressions. They're also huge, so you can resize them to whatever you need.
The downside is, these are not available as PSD, just GIMP's native format (XCF). This is because I used layer groups quite heavily; I don't know if PSD format includes layer groups or not, but GIMP if it does, GIMP loses them when it exports to PSD. I'm not gonna disassemble all my layer groups manually, so short of finding an automated solution, XCF is all I've got. Sorry!

Backgrounds

Here are the backgrounds for WAG (All in one zip file). These are all just filtered photos, some of which came out quite well... others, not so much ^^; Oh well, you can use them if you fancy! Credits for the original source photos are included in the zip file.

Here's a 4-frame animation I used to create rain over my 1024x768 backgrounds in WAG. Looks kind of bodgy in the little preview GIF, but I promise it looks pretty good in-game.
This one is CC-BY; I really don't mind how you use it, as it's just a collection of GIMP filters and a few lines of code made from directions here on LSF. Ren'Py script for declaring the animated image is included, so you can just drop-in and go!
