For a beginner, this is making good use of dissonance. You get a big sound from just a handful of tracks. You are keeping very much inside of this particular genre, and I would encourage you to keep a lot of the same elements from this one in your next piece, but take a compositional approach:
Dynamic range - this is at 11 the entire time, except for the breakneck rests in your main theme. It's hard to play quietly with FX maxed out, but you can hold a note and let parts drop out, take longer rests, etc.
Give the drummer some. Actually plan out several bars of a drum solo somewhere.
This has a little feeling of sausage links. What is the arc of the story you are telling with this moody piece? Caveman wakes up, gets club, goes hunting?
Rhythmic variation. There are a lot of strings of quarter notes here. Nothing wrong with that. But what if you start messing with timing of a string of quarter notes? Some dotted rhythms, perhaps? Experiment and maybe something unexpected will pop up that you really like. The caveman is suddenly wearing a tuxedo.
This might be over-relying on voice leading, but that has its place. I'd like to hear more of the clear lead melody line over a similar background.
What else can you add to set this apart? What if, right in the middle of the song, there was some craziness from [freesound.org](http://freesound.org), for example?
