Hey there @kuchenchef
Really nice sounds in this one, like the ambient & chill feel and the minimalist approach for the overall beat & the drums elements, it's making room for the nice synths layers, those are playing very nicely together IMO. The top & main lead synths might be a tiny bit too much in the front comparing to the Bass & Drums. Not too much though, you have to preserve that minimalist drums sounding in this track I think, so yep, the perfect sweet spot for level adjustment between elements might take some trials & testing. A few dB down on the overall track master level could help too.
For the duration of the track & what could be next, well I was expecting a break when I reached the vocals at around 2:22, if you remove all drums at this point and just keep those vocals & one sustained synth sound ( nothing arpeggios or rhythmic ) and maybe some background noise like you used in the track, you should get a good start for a nice break and even a melody or new instrument insert that might inspire you for the rest of the arrangement.
Nice one good balance between a dark & chill feel when listening which makes it pleasant btw.
