Nice developments of motifs though they are similar to some already out there... And i like the use of instruments, perhaps could have extended the climax more? Has a lot of potential!
Love this - i hope to build towards this! And Hans Zimmer is definitely a favourite for me! You've re-created his melodies well - maybe add some more layers for development purposes? Could i also recommend a piece worth listening to which your piece reminded me of - the soundtrack for Requiem For A Dream. Thanks, great composition.
