Grumpy old git moans aside, what I really want to say is that layouts like this are so, so easy to come up with on paper, as it were. Lets face it, there is nothing new there at all. But making something so basic look so elegant is the real art.
Yeah, there are nitpicks, but I'm sure you'll smooth those out. The bulk or core is bang on.
As a lazy useless git, I wouldn't mind a template of it!!!!
Nice work.
