Pyzelda, this resolution is too low... If the sprites are 32x63 pixels, we'd have to have backgrounds with more than 640x480 pixels, maybe 1280x960 pixels (since I'll use zoom and scrolling engines).
In this game, background drawing is more advanced than spriting, because you'd probably have to work with Photoshop or use vector art...
Sorry, but you'll have to put more effort into your images, otherwise I don't know if I can let you be in the team.
