Of course it's short, it's a preview.
But that's besides the point. It is a little slow at the beginning, but then it picks right up. Maybe ahorten the intro a tad? I can see it really has potential, and I know your a great audio artist. Keep up the good work!
Good but too short
I like the track espicially from 0:40. But then it just ends for too quick. Try to make another version, a version which is much longer.
Please contact me if you would like to use this in a project. We can discuss the details.
