Quite good indeed for FL! =D
Your drums are quite impressive there! Some good shit (do you listen to a lot of metal)? If you do, you'll notice the guitar isn't quite there though =P
The only way to get a "good" guitar in FL is to use a few of them... One with a palm mute sound, one for the melodies, one for rhythms, etc etc. Which I never did in fact. If you check out my early songs, they're made with FL and they fucking suck balls. Your little piece here is gold compared to what I did with Fl back in the time.
Now however I got a guitar and I must say that's in fact the only way to make real good metal, so hurry up and buy one ;D
But srsly, overall nice song dude! 5/5 cheers!
