Guitars don't sound too bad. The weak link is the drums, particularly the snare. The snare is clearly programmed and it has that shotgun effect, including where each hit is identical in velocity. Then, the snare is placed into a different space by its reverb, which seems to differ from the reverb on the guitars. I hear two different rooms in the song, and it adds to the artificial feel.
Can you tell us how you recorded these sounds, and how reverb is applied throughout?
