The shadows on the well look much better, though.  They're not so dark that
you can't make out details.  I like this a lot more than the previous shot. 
It's got a lot more realism.

Actually, the background color does affect radiosity (take a look at my Door
into Summer pics recently posted.  The wall on the Summer side are blue,
despite the light being yellowish because of the sky) so I don't know that
that's necessary.

My one complaint, and this goes for many radiosity pics (including mine), is
that it looks a little plastic.  Adding appropriate finishes will probably
fix that, though.
