sample of a song i've been working on...

No need to ever apologize for your genre, TMO. You'll find that most folks around here are musically omnivorous. And anyway, most technical aspects of music production are common across all genres.
 
Metal's not my thing, but mostly because I feel it's overly derivative. Metal fans are very specific about what a song's got to have in it, and if you deviate too far from the formula they'll reject you for not being pure.
 
That said, your tune's got potential - my advice to you is to remember that it's your song and that there are no frickin' rules. If you want to throw in a banjo, do it.

Very promising. I wish you could somehow put a bass instrument of some sort into the track to further improve your sound. The playing was very good and if I am not mistaken a bit Metallica style.

bass and vocals will be added. The bass is going to really stand out in the intro.
...and yes, you're correct in the Metallica influence. I've always been really into old school metal (Megadeth, Iron Maiden, Ozzy, Pantera, etc.)

Now all you need to do is keep working it till you get it done.  Sounds great! Don't forget there are people you can collaborate with here in the forums if you want an instrument you can't play or vocals if you don't sing
