Beautiful.  The left edge looks a little strange near the bottom.  Not
certain what's going on with that.  The bottom edge also looks somewhat
abrupt.  Flat is ok, but it's awfully solid, I think.  How did you get the
top to be fluffy like that?  Can you give some hints as to what kind of iso
you used?
