Cool vibe, but...
I actually really liked what you had going in the first ten seconds of the song. The strumming of the acoustic guitar coupled with the electric guitar was very nice on the ears. When your vox came in though, the vibe slipped a bit. There were a few notes your voice struck that were definitely disharmonious with the riffs you already had going. However, the stereo effects were well-applied.
Trust me. It sounds better without. I was just experimenting. You can't hear the harmony of the guitars. I'm thinking about uploading without the vocals, too.
Edit - Infact, I just did.
