Sounds like a metal ballad!
Here's my tips :
As for production, kick sounds pretty decent...but I'd say you should find a new snare sample, quick. Then learn how to mess with velocities a bit so that part around 3:30 where the snare goes from 4th notes to 16th notes sounds a bit more natural.
The song is thin on the low end also, you sorta got a black metal thing going on. Haha! The bass guitar itself is plenty loud, I can hear the notes perfectly...so maybe dick with some different EQ settings. Or better yet, change the settings on the Line6 thing before you even track the bass.
Now here is where I get really subjective, and by no means, please don't take anything I say in a bad way. I whole heartedly believe in constructive criticisim, not destructive.
Admittedly my taste in music a bit off-the wall...a bit experimental, but I think you need to change up the writing to make it a bit more interesting. Even if you did bring in a singer to do vocals over the first couple verses and choruses, it would still be a pretty monotonous song. You need to give the singer as much to work with as possible. Even when you changed up from the chords to the palm muting, you were still playing the same notes.
The entire five minute song is non-stop guitar, from front to back. Take a break with the guitars and give your bass and drums some transitions or something. Let them take you between the parts in your songs a few times. Letting the other instruments shine a bit introduces more dynamics in your song writing.
Now having said all that, this song isn't bad by any means...and I'm sure if this were thrown on an album with a full band it'd sell some copies...but personally, I like to hear a bit more variance in my music. Something new, something I've never heard before.
Cheers!
