yet another metal fan joining the legion of composers! MUHAHAHA! ;)
i used to be HIGH on BG, kamelot, symphony X, rhapsody (though fabios voice is a pain in the butt) etc. but recently i turned 100% classical :P.
now, i heard your piece a few times and i can say its pretty darn cool! interesting combo... electric guitar, cello, bass, triangle (?), piano euphorium... gets the job done though i must say.
first of all i liked all the melodies and the general idea is very cool! ( especialy liked that part with 16th notes in the euphorium XD). the instrumentation is quite good too, however the harnomy was weird at times ( and not the good kinda weird). like the piano solo part (page 9 i think) had a great melody, but sounded unsatisfactory with the left hand... maybe you should see something about that. also the last measure on page 8, where all the instruments hold that e-g-b... kinda disrupts the melody that followed. i notice the totaly random ending XD. not sure if it fits, but hey, if you like it keep it!
thats about it, hope i helped... good job and keep composing!
