I may be in the minority here but I feel your reel is very very long. You have some excellent imagery in there but much of it is repeated or held on the screen for too long. Sometimes sequences have more impact and are better represented by quicker cute.
For instance, the woman manipulating the minority report type screens is cool and well done, she shows up multiple times in your reel and for long shots. The viewer could have gotten the sense of the project in 5 seconds or so instead of the 20+ she takes up.
Almost 5 minutes of a reel is tough for me to finish. However I am new to this forum so take my opinion any way you like. If you really like how the reel plays out then by all means keep it the way it is.
