Okay
Act 1: The kick drum is really weak. Personally, I would go with a kick that has more or just a better sounding low end.
It sounds like you're using VST guitars, right? Ouch.....It's pointless to complain about vst guitars not sounding "real" but I can safely say that unless you get real guitar or at least really good samples in this, the song will never realize its full potential. I think I hear a bassline in there somewhere, but it is way too quiet and gets buried by everything else. I would say that a lot of the leads could be dropped in volume a bit.
All my complaints about act 1 apply to act 2 as well. The songs themselves are fine though.
Of course, these are just my opinions.
