Think the first two are great – you have a real unique sound in there. If your goal is library – and background music – on the whole I would say make things less busy, tighten up the timing in places.
I could see the first one being used on a kind of quirky or strange docu-series. Like the Dark Tourist or something similar. It’s kind of upbeat but dark at the same time.
Lot of good ideas; I’d start upgrading your libraries for a better overall sound. I can definitely hear some possibilities for advertising. If you’re not using a DAW, get one and learn everything you can about it so you’re fluent with it’s features. Keep up the good work!
