Yes, It's easy to keep thinking you must add more and more but sometimes just taking something away can be what you need! It can be really nice when a song breaks down into something quite minimal and then builds back up. I feel like that's the sort of thing that could work quite well in your style of music especially.
Another thing I've been trying lately is when I have a complete song structure laid out with drums, bass and at least a couple of synths playing is to then find a sound/instrument that works nicely but only use it in a couple of sections - nothing more. I'll then repeat that with another sound until I have at least a few scattered around in there. They just add something fresh to what otherwise would've felt like the exact same thing repeating.
