Ah the kick, yes, you're right. I probably went with a softer kick because of the drone origin.

Also, I'm still having a bit of trouble mixing the kick drums, it usually gets lost in the lower frequencies and I have a hard time making it cut through the bass, so using a softer kick with shorter decay time made the mixing a bit easier. Then I also added some EQ in the DAW to remove some frequencies and make it fit better with the rest of the sounds.

Overall I think it sounds better than in my other mixes, though it doesn't sound strong enough for a proper techno track. Yeah, that's something I'm still working on and needs some improvements.
