Orchestral rock definitely fits the art and I really like where you started with this. Solid idea but needs some refinement. Easiest thing to fix, not that it's easy but doesn't require anything than your own ears, is the mix. I love drums and the percussion needs to by punchier. The drums have great tone and sound great, but because they're very short sounds you can get away with cranking up the volume of the percussion (although careful with cymbals, they're not as short). Could even throw a compressor on them to bring up the volume a little bit by controlling their peaks too. I'm not fond of the bass sound starting at 1:25 section. It sounds cheap in comparison to how you've got your other instruments and especially on its own. You could probably get away with it if you layered it with some other bass synths or if you wrote it so that it wasn't just static quarter notes and half notes. Most people would say "you need to buy better plugins man" which fancy sounding plugins will always help the sound sure, but you can also find ways to make you cheap plugins sound good. There's tutorials on youtube that you could probably find to help understand what sounds your plugins and VSTs best fit. It's getting an understanding of what makes your tools work best and where they're weak. To make an analogy, it's understanding how to use your hammer for nails and not your shovel. Sure you can use a shovel for nails, but it's better for other purposes.
Again I love what you've attempted with this. 0:33 has a great beginning idea you could use, but rhythmically outside of the melody there isn't much that's as interesting. The counter melody you brought in at 0:59 is something you could really develop in other instruments/phrases/or what have you. Like for example at 1:56, instead of just bringing in the lead guitar the way you did, I would have reintroduced the counter melody again with more subtle instruments and rephrased it in a different rhythm or something to make is sound different but the listener will still find it familiar.
Again really enjoyed it, and both the song and you have solid potential.
