Template practise

After a couple of weeks I've finally finished coding a template.

I followed the photoshop tutorial first here...

Then figure I'd challenge myself trying to code it.

My effort is here....

There might not be much to comment on per se, as I didn't create the design. I have for the most part achieved the right look. I'm more concerned over whether the code would be considered 'clean'.

I'm a little iffy on the buttons and would welcome any other ways to do them. Having them as inline made positioning a little tricky.

Hit me with your best feedback, good or bad.

Thanks!
