i had a listen through the rest of the tracks and you seem to use the same electronic backdrop with all of them. For variety's sake, i would say experiment a little more, go outside what you might consider to be your boundaries and you might find something of value. Experimentation is a dangerous thing though, too much and you could really fvck everything up, too little and everything will just sound kinda samey as the current situation. The music sounds all well and good, but if your primary influence is NIN, just look how much Trent Reznor experiments... Just a suggestion.
