Hi Alexander, I like this song, it's obviously straight from the heart - the best one's are. It's full of honest emotion and it reminds me a little (in a good way) of Dream Theatre's 'take away my pain'. I will be interested if you post a recording of it because I think it's long enough to need some clever variations to keep the listener engaged (e.g. quiet, reflective sections, stops in the music, louder/quieter parts etc.).
I do agree with Jess about some of the rhyming, but often that can be completely countered by the way it is sung. I would have another look at:
* The word 'die' in the first line seems a little blunt, which would be great in a heavy metal song but maybe 'have to go' or 'have to leave' would say the same thing. Using the word 'die' in the last few lines feels absolutely right though.
* The word 'knight' in line 3 - apologies if I'm missing a double meaning there - should it be 'night'?
* There appears to be a few grammatical quirks, like using 'to' where you need 'too' - easily sorted.
I suspect English may not be your first language, but either way, well done! This is a cracking song and I can't wait to actually hear it.
best regards, Graham
