Remove the background separators from the navbar, they aren't lining up well at all - the same effect could be achieved by giving a 'border-right' to each of the menu items, with the except of the last one.
Get some padding and white space into the design as well - give the photo room to breath, and have a look into a grid - so everything flows nicely. For example, the left-hand side - the logo, nav and main copy all sit at different spacings from the left border, make this uniform for all elements.
