Yeah, it does have a bit of darkwave feel to it. I'd say calling it industrial/darkwave is a good descriptor.
You should put vocals on this track, mate. Like at 0:36 I thought I was going to start hearing Dave Gahan singing.
If you aren't going to use vocals, I'd say to use more variation.
I think there could be little bit of a more diverse sounding instrument field. Your two lead synths sound generally the same. I love when you have that gated pad/trance synth or w/e you want to call it comes in. Really gives it a darkwave feel.
The mix is pretty nice, but the two leads are a little astray from the rest of the mix.
The ending... Leaves much to be desired. It would have been better if you had suddenly stopped the song at 2:50.
I think this is a great idea that you could easily expend on. It does sound great, but it's a bit repetitive and needs more synth variation.
