Re: Null Wave - Rats (110bpm like Apparat inspired dance)
I really like this. It has a nice ed banger - SebAstian feel.
I like how you've spread the stereo field, and everything sounds pretty crisp.
Structure: The intro sounds great. When the kick comes in at 0:35, it sounds like that might be where the main chorus should go? But, it does continue on, guiding the listener to the next journey, but then there isn't a full outlet or expression/chorus at an one point. Perhaps you could include one more element in the main structure and have that repeat a couple times in the song. From how the song is set up, it seems to cater more towards this style. If you are looking for something more progressive that tells a long story, then maybe be more light and smooth with your introduction to sounds as it progresses.
It needs more transition sounds that create tension and anticipation unless you are trying to go for more of a bare-bones techno feel.
Sound design: I like the sounds you used and they all fit well. You could experiment with adding more or less of a swing to see how it feels. Work more with effects on the sounds. Actually, overall on everything, use more automation to make it more organic. Change a filter, put something really far away using delay or reverb, bring it close, take it far away, try flanging something...
I'm listening on headphones so I can't give you much feedback on the mix. It sounds good with headphones.
