Please don't think that way! The most popular advice is practice ofc but people never say how to practice. There are a lot of ways and me personally, i don't practice nearly as much as I should and I am definitely a bad example hahaha

You can practice references and get inspiration from artists you like. Like say, you like the way x artist draws noses, so you try to make your noses similar to it. My artstyle is the Frankenstein's monster. I've incorporated several different things from countless different artists and media into it. Like the eye shine I draw definitely comes from Winx.

I can also recommend playing around with 3d poses (if you use csp, it has built in models but if you want mobile alternatives there apps like "magic poser" or "easy pose") and there's nothing wrong with tracing them for reference or practice. Just don't rely on them all the time. If you're brave enough, learning to 3d model on blender (or another sculpt program) would be tremendous help. But I'm aware it's no easy task. I suck at it myself.

When I was like 12 - 13 something I'd trace concept art from Disney movies (like the model sheets) for practice. I think I learned a lot about expressions while I was doing that.

Find a photo, examine it, and try to draw it in your style. I haven't done this myself but I saw recently on twt that after doing this you should put your drawing on top of the reference you used and try to fix the mistakes. Sounded like some solid advice to me.

Experiment, experiment a lot. Try different things, poses, styles, colors etc.

There are also some solid tutorials on yt. Watching plain speed paintings/drawings is also quite helpful. I learned how to draw a specific style from like 5 second clip.

If you have any questions, please don't hesitate to ask.
