Well the clouds were based on this photo:
http://groups.msn.com/XPCenter/windowsxp.msnw?action=ShowPhoto&PhotoID=42

But then I softened them slightly. I have tried some differently lit versions,
with the light a bit further away so we get less saturation of the whites, but
it just looked too dark for the sunny feel I want in this scene.
