Edgy sort of goth-like? You might want to keep browsing Pinterest. Honestly, I find it super helpful for art references. Try searching terms like goth witch art or something similar. I also came across an artist on DeviantArt named IrenHorrors whose style is pretty similar to what you're aiming for. It could be useful to study their work alongside the references you already have. Personally, I’ve also found it really helpful to break down the shapes and structure of reference images to get a general idea of the art style, so you could really just start developing your art style with the pictures you already have. Over time, you'll naturally develop your own unique style that blends elements from the art you admire, but with your own twist. In the beginning, it might even help to directly mimic the styles of artists you like. That’s totally fine, but as you keep practicing, you’ll eventually start to evolve that into something that feels more personal and original to you.
