Nice job man! This track has some serious potential. I feel like it could use some stronger sidechain/ducking, but I get that this is supposed to be minimal and less strong feeling, so I won't include that part in the actual rating. Everything seems fine to me, although I don't know exactly how this style is supposed to work because it's not really my kind of genre, but really the only noticeable thing I could find that could be fixed is that the crash is far too loud and blurs out everything with the amount of synthetic white noise. Otherwise, fantastic progressive minimal house you have here :)
Also, great choice of VST, I use serum for literally everything in my songs, it's an absolute boss, despite being quite cpu heavy :P
