1) on my ipod touch, the site text is small and squished to the left
2) the blog title/tagline is off to the right down by the content seperted by a big chunk of real estate
3) your background image is 673K (nice tree) but you should reduce the quality and dimensiion - does it really have to be 1800X1350?
4) in your header.php you have multiple div's with the same ID - ID's are suppose to be unique on a page, classes can be duplicated, but ID's should always be unique
