I really like the beginning of this. Not something you would expect to come from a metal song. I could tell where it was going though, and it had me really excited. And then when the metal finally entered at 00:59, I had a hard time hearing the main guitar lead. The backup guitar seemed a little to overpowering, and the drums didn't feel like they were punchy enough. One suggestion I have that could help: maybe take the lead guitar up an octave when it's playing the main theme (like at 01:00). I bet it will make it a lot easier to pick out once everything starts playing at once.
I like what you're doing at 03:04. It's a really cool blend of what the beginning theme was, and what your metal was doing. I feel like it started entering the rock ballad genre at this part, which isn't bad.
It also feels like when you were trying to play the main theme at the 01:00 section, it also sounded a little empty. The only thing I can think of is that if you quiet down the back up guitar and have it play a little longer it might help. But I'm not an expert in the metal genre, I just occasionally listen to metal.
I like where it's going, but it needs a little work.
