Favicons

I added a favicon to my blog - the little image that shows up to the left of my URL in the toolbar. What do you think? Does it actually look like a hazelnut at that size? I'm wondering if I need to get rid of the shadow...

ETA: I got rid of the shadow - but I don't know if it makes it better or not! Or maybe it doesn't really matter, I just like that it's there.
