I have to say that there is nice contrast between the happy sounding intro fantasia (life) while a minor mood from the guitar/strings(death). I especially like measures 37-44, you've got a nice blend of instrumentation an the guitar riff there in measure 53 to 60 is creepy as hell. I definitely like the fact that you are adding some melodic style with your metal; I think with a little extra effort you could make this into a really good song
