The outside is a lot crisper than the inside. It isn't necessarily a problem, but I noticed after looking at it for about three seconds. I'm not sure if it would help, but perhaps try a more clean-cut font or reduce the fuzziness around it? Worth a try, I reckon. Nice work, by the way.
On an unrelated note, would someone be so kind as to put some transparency around this little bunny avatar of mine? It looks funny. As for why I have a small bunny as my avatar, see my post in the "sexy/violent avatars etc thread", I'm doing an experiment. That's my story and I'm sticking to it.
