The site looks a bit "ripped apart". Logo and Nav to the left, "Welcome" all the way to the right.
Easy fix though: Take the "Welcome" out, people are already there, and you "saying" welcome is not going to make them feel more comfortable.
Think about centering the Logo and eventually bring the Nav Buttons horizontally - center to the top of the screen, below the logo.
The categories are well placed, however, the search bar is completely misplaced, bring it center - below the Nav Buttons.
Other than that, the site works just fine: :tu:+1/2 out of 3
