Cool track..what I heard of it, anyway. It's kinda hard to leave meaningful feedback,, when you don't have the whole track to listen to..and I take it this is not
the whole track, seeing as you have "preview" in the title.
That said, based on what I did hear..the start could do with some sort to riser that morphs into the track..as it is, it's just a tad too sudden the way it kicks in..to me, anyway.
Also..those vocals..I really like them, but I think
they could be better if you cut the low end a little, upped the gain a tad (not too much..just a little) and added a little reverb, regardless of it you added some already or not.
That's it..loved it..just wish it was a complete track..as it is, I kinda feel bad about saying anything, as I don't know what way you're taking it or what you have planned.
Hope you post the finished track up here when it is done.
