It seems pretty good to me, design-wise. It's easy on the eyes and fairly straightforward to follow.
If you want to use a static front page, I think the very first thing visitors should see is a banner or cover for your story, along with a brief summary. Right now, the first thing I see is a note saying that "fan art will be accepted" - a bit off-putting, since I have no idea what such fan art would be for!
Make sure it's ultra-clear where I can click to start your story or read the latest chapter.
I also have to ask you about the PayPal Donate button - when I tried to get one for my site, I saw a message saying that their donate buttons are for registered charities only. Did you see any such message? You'd better check with PayPal - my understanding is that they are getting more strict about that.
