To add a little professional perspective in here but perhaps while... not being a jerk about everyone else's pretty valid opinions on a nuanced subject... You don't necessarily have to have just one style, and there's really no need to deliberately try to develop one.
When I approach a project, I decide how I'm drawing based on the project. I have a sort of "default style" which is how I draw and colour if I don't spend time deliberately thinking about how I draw, ink and colour, but even that is always in flux and always evolving. It's not necessarily a good idea to pin yourself down and say "this is my style now, this is how I draw eyes, this is how I draw hair" and then to not give yourself that room to grow and find better or more flexible ways to do things.
If I need to do a job where I must accurately capture a person's likeness (which I had to do on the BBC book "Doctor Who: Women Who Lived") I might push my style a bit closer to western comics with more naturalistic proportions and soft shading because it gives me more control over face shapes and lighting that matches specific scenes or places from that live action show.
If I need to make a webcomic to appeal to modern webcomics readers, like Errant, I let my weeby manga influences show through for an expressive, dynamic look, and go for simple cel shaded colouring that's quick to do so I can keep up a schedule.
If somebody wants digital painting, I tend to do more naturalistic proportions because that's usually what people who want that style are looking for, often for D&D campaigns and the like.
If I need to do cute mascots or sketchnotes to make tech events or talks less intimidating, I draw in a dot-eyed cartoon style with kind of chibi proportions, and I use warm, toy-like colours and shiny cel-shade rendering or minimal colour for speed and readability.
Because the thing that makes my style what it is, isn't just "she draws eyes like this" "she draws noses like this". It's more in how clearly I get across the intended meaning with relatively low detail, allowing a few strong lines with tension or relaxation to create a lively, dynamic look and very "readable" drawings.
So when you see a comic I drew when I was 22 or 23 years old....
It's not in colour like my current comics, the line quality is different, the level of detail overall is different, the hair is rendered differently from my webcomic, I drew noses differently.... but if you see a more modern page of mine...
You probably wouldn't doubt that these were drawn by the same person about 14-15 years apart. Because you can see the Nomura, Kishimoto and Arakawa influenced proportions, the bold lines with strong line weight variation used to get across the tension in poses or the flow of fabric and hair, the simple, exaggerated expressions. (and the preoccupation with ladies with oversized swords exploding monsters might also be a clue...).
So if you're trying to develop a style, focus more on trying to express what you want to express. What energy, what emotions, what kind of vibe... and look at artists who evoke that feeling for inspiration, taking on ideas from what they do really well, but combining lots of different bits you like. You can pick combinations of vastly different artists for this from different countries, different media or genres... it's all good! Don't be scared to change or branch out; you don't have to just decide on a style and stick with it forever or use it exclusively (I'd have been screwed if I'd refused to ever draw in a non-manga style during the 2010-2016 Tumblr era where drawing manga style was suddenly extremely unfashionable).
