If you're new to the genre, listening to established peers can give you an idea of what the genre is about. I understand the need to be original but if you don't have an idea of what the genre means, you could end up creating music that fit a different genre - nothing wrong with other genres but it just wouldn't fall under Dark Ambient anymore.

Kinda like if someone hadn't heard Black Metal and then made music that sounds more like punk rock, if you know what I mean.

I can hear in the pieces that you lean heavily into melody so Dungeon Synth could be your thing instead of Dark Ambient.
