I agree with some of what Tom said. The reel could be shorter. Maybe 1-2 minutes. But overall, I think you clearly have plenty of material to demonstrate a true proficiency with the medium. So yes, to echo Tom, I'd cut it down and keep only your best "money" shots. Who will be watching this? Ad execs? Directors? Pick an audience and cut it how they'd want to see it. As for me, I can't even watch a video online if it's longer than 60 seconds unless I force myself through it.
