It seems nice, but that blue bar of which is the background of the "Video" link, is detracting the eyes. The eyes would be distracted from the actual content because it heads to the brightest colours. You are making the selected link, "Videos," seeming as if it was important. Get rid of that blue bar, and also try to tweak that selected background (Videos.) It seems too... blobby, or something. Keep on tweaking it a lot of it's aspects as far as the sidebar bordering, and the title heading.
Thank you
