I liked the climactic intro and the distorted instruments, but the part after :50 got a little repetitive, and I didn't like the effect you used at 1:04. 1:14 was a bit of a rough transition, but maybe that was just to give some finality to the preview. I listened to the whole thing on Youtube, and I liked it in general. Some of the transitions were a little cliche, and it got a little repetitive after a while, but pretty good job. Keep up the good work. ;)
The song is ok, but i hope for a bigger sound level on 00:50, but oh well it was good.
Please contact me if you would like to use this in a project. We can discuss the details.
