Slayer?
You're right - you aren't the best at FL. But this is still a darn listenable track. You have some glisses and other nice little touches like that, but it needs more mastering. It's all at the same freakin' volume...get some crescendos happening!
More layers would be nice, too. Get some ambient stuff going on, and please please please get more drums. I'm just not feeling it.
Also, Slayer kinda sucks. :\
You're well on your way! It's a good mix, but it just needs more.
