hello there, Esca!
i listend to your piece, and i must say it's really inpressive and in terms of sound itself you really did a great jot bringing the might of the Leviathan to life!

With the brass sections powerful and the strings creepy as hell the sound you made gets really amazing.
but its noticable that you dont have a great deal of knowlage in music theory and instruments. some parts were way out of range especialy the chimes (or tubular bells)... i know it sounds good when they are played very high, but their range can go up to a second F above middle C im afraid...

. also timpani can only go to a D below the bass clef and you even used an F# below that. But dont worry! maybe using the bass drum those notes can be played. aslo- in the brass section you had an E3 at the very ending... a trumpet COULD play that bu only a REAL virtuoso! i think you should learn more music theory if you plan on getting your pieces performed, but if you are planning for them to be only recordings then the music you worte works pretty fine!
even that the harmony seemed like a compleate mess when i first looked at this the sound was pretty amazing! and yeah, i saw stravinsky influence in those bitonal chords. but as for the melodies and counterpoint, i'd say more like.... mussorgsky? maybe a little borodin from time to time i think, am i guessing anything

?
ok well anyway it was a really interesting piece to listen to and i think with help of some music theory you can make it much better! just keep up the good work! hope to hear more from you on the forums ,
