Pretty nice
A few things to point out.. the distorted tone in comparison to the clean intro were really quiet, and the same can be said for the drums. I use sequenced drums myself, but they can sound a lot better if some variety is given to the beats, as I noticed throughout the heavier parts, the drums were playing the same beat.
As this is a demo, I won't mention anything about the quality of the playing, but do remember to keep that all top-notch when you record the final version.
Overall, it's a nice demo, it just needs some tweaking to get it to its full potential.
