It starts to sound a lot better, but there are a few things that I would adjust.
Firstly, the intro needs to be lower in volume, and also another, softer instrument. Maybe add some vibrato to it, a bit of reverb, just to make it more dreamy. Maybe even set it an octave lower or higher (depending on the instrument you use). Just make sure it doesn't overpower the other melodies that are more important.
Secondly, don't cut the first part (at 0.20) when the second melody is playing. Let it continue and blend into the part where the cymbal plays (at 0.27).
Also, it seems like the 'choirs' between 1.59 and 2.03 are a bit out of tone with the other instruments.
And, maybe let the ending be more fluidly, and not so abrupt.
Other than that, it's really starting to sound great.

Oh yah, one more thing, don't be afraid to add stereo in your music. By that I mean, give your instruments a place in your songs (left, right, centered...).
Slayer rules!!! Yeaaah, man!
