Looks nice, thanks a lot.
The only thing I would suggest to change is probably the typeface, it
you could find a smoother one. And I also like having "j" in italics,
if possible, although not I don't insist on it.
I think it could be used as a default logo for jGrouseDoc distros and
on GoogleCode/GoogleGroups pages. And I would keep the clunky one for
jGrouse itself, until someone would come up with a recognizable
picture of a hazelgrouse (for personal reasons :-))
