I think the length of the reel is good, but I'm not certain what it is that you do exactly. Are you a producer or an editor? A lot of times these reels can look very similar, so I always find it best to name the reel wherever you are presenting it. In this case, I might even add it to your title slate as it's not on your own personal website.
As for the body of work itself, you've got some really interesting stuff going on, and some good clips selected, but I can't tell if you've got a good balance without knowing what kind of work you want to do.
I hope this helps, I can tell you have drive and talent so you shouldn't have a problem ^_^.
