The only issue I can see is a XenForo one. The login/signup drop down thing, just breaks the flow for me. Personally I would integrate the login form into the design in the top right, it has the space. And you can even do it in relatively small areas using a method I used here -> http://savagerebirth.com. Decided to see how it looked when logging in. How it looks reinforces the idea of the login form there without needing the extra click because it will change the login form into your user options which will be a nice subtle effect. Hell you could login with ajax and fade out login and fade in user stuff However that would be a bad idea due to the rest of the page showing for guest... would be cool though heh.
