Looking for general feedback on some screenshots

I've been working on an update to the Comic Zeal interface. I've not been happy with how rigid the look of CZ is and theming is something I've been meaning to do for a while.

For the last couple of days it seems like I've made almost no progress on the appeareance of the app and I think it's because I've just been looking at it for too long without any outside input.

So I wanted to show you all what I've been up to and get your feedback on what you see. There is still work to be done but it would help me to get some sense of what you all think about what I've got so far.

What are your first impressions about what you see above?
