It was original, diverse, and had lots of effort
But I have to agree with Redbull to some extent. It's clear that you know how to handle a guitar, but it sounds like you're trying to show off all your techniques in one song, and that never works. I'd rather hear a song comprised of 2 or 3 amazing riffs instead of 12 average ones (that's why I don't listen to psycho death metal). You definitely have the skills to make a really great metal track, just remember that one song will not impress everybody.
