Damn... I'm personally not a big fan of metal (aside from Metallica, that is), and as such, I was a bit skeptical towards it from the beginning... But I really like the tracks you linked to. Sound freaking awesome, especially for someone who's only played for a year and a half! Keep it up and you're bound to become an even greater guitarist!

Edit: Oh... My bad. I had only noticed the first track (Save Me) was categorized as "Metal". The overall mix is actually pretty frigging good. Keep it up!
