Dejavu: I love the sound of this reversed guitar! Very cool, yet after the third or fourth repeat, the ear desires a bit of a change. In essence, this is 8 bars of music repeating again and again.
Main Theme: this guitar sounds similar to the one from Dejavu-- perhaps you took it, tuned it up, and reversed it? Either way, once again my ear craves a bit more variety-- and variety is delivered with the really cool breakdown section.
Nice work, and keep writing!
