Hi! Glad to see someone's working on this. :)
Just a quick design tip... When dividing a layout into different sections, it's often best to use negative space instead of additional elements. For instance, the mockup at
http://i.imgur.com/YLUvp.png uses two grey lines to separate the three sections. However, some whitespace would be better suited here and you can see that if you simply remove the lines (

If removing the lines would have made the layout fall apart, that could have been a signal of deeper problems. But in this case all seems fine, so apparently the page was designed well. :)
Tl;dr - the grey lines can be removed because they are not needed.
