Not bad, but did you try to write a sequell to Dream Theater's album "Scenes from a Memory" ? it seems very close to it, with some commun riffs, and I am sure of something : about 4:00 in "Plunge into Hyperreality", it's Universal Mind, by Liquid Tension Experiment!
You have great inspirations, but try to make something new, more personnal, and not a tribut to the the best band ever!
