Wow, nicely done. Wasn't expected updates like that so quickly. I think the hat was a great idea too. My wife is seeing it too and she also likes it.

As far as the quill, you could model the shape of it and then make an alpha map to use for the transparency. That way parts of the edges are transparent so it looks like feathers. I don't really know how to explain it any better and I don't have any experience with alpha maps. I just know how they work at this point. Perhaps someone else can explain it better if you've never done it before.
