NCIS!
This is probably one of my favorite TV shows and I love the theme to it so you automatically get respect for that!
Now while you have my respect for actually taking up the request for this song... I will agree with Ztrl and say that the bass is a little loud and seems to overshadow some of the great melodies in this song. Not to say that its bad... I just love the melodies in this theme. They're so catchy.
Anyway, great job, keep it up :D
