Typos on the "SponsEred" when you click on the tutorial links.
It's a nice domain. It would be better if you could write/hire people to write own tutorial instead of linking to other pages, use a CMS with 2/3 columns (for menu, links..), remove the banner until you start having real visitors.
* Header graphic too big...lot of useless space - the 2 blue strips(you can do without them really!)
* I personally like to brand my product and services. Your header should have the website url and the name - clear cut - no exceptions. 2 or 3 visits to your site and "YourTutorials.com" should be the place to visit for any tutorials! Why be just one of the many tutorial sites out there, Brand Your Thing.
* Grey with white/blue text is good - no worries - looks professional. Decrease the page width though.
