The bar for "RECENT SEARCHES" should be rounded off on the top edges. Maybe try and even out the search bar with the drop downs. The font in the logo feels wrong. Could do a little work on the navigation of the website. Otherwise it's nicely done. The blue and white colors are nice, And the implementation of "Bookmark & Share" is well done.
Overall a good design. It's simple and its clean. Colors seem to be fine and match accordingly with the design. Not much to suggest, you did a fine job.
