My favourite Depeche Mode Album was Violator and I think you captured the feel of this song rather well.
The mix is a little messy, though. Might want to remove some freqs here n there, but my main gripe with this is that the melody during the chorus, or bridge, or w/e is a synth that is far too similar to the other synths being used and it becomes obscured in the soundscape. (in other words: it doesn't stick out enough).
I suggest using a different synth there. (the part that starts at 0:45). Pretty cool, though.
I'll admit: I'm a noob when it comes to mastering songs, especially EDM tracks. I still have a lot to learn about compression and EQ, though I completely understand what you mean when it comes to the 'lead synth'. It doesn't stand out. I'll improve on that in future songs!
Thank you so much for your review, I really appreciate it! :)
