A very engaging intro, I would have maybe drawn it out a little longer. And that lead that comes in, while awesome, may have come in too early as well. The percussion is solid. Your accompanying synths that back up your lead could stand to be a little louder because they are beautiful. Very nice. This reminds me of a Deus Ex track in some ways. It kinda loses me there for awhile during the 2-3 minute mark. It's not bad but it doesn't evolve into anything else. And it ends a little too abruptly. All in all it is a good track and I enjoy it. I would just make people savor it more by adding a little more time for it to establish itself. Give it some ambiance and if you're going to end it, end it with a bang. Nice work though!
