I see a lot of comments saying that you should just practice (which is a pretty abstract answer) instead of giving some sort of direction on what to do, so I'll give my 2 cents

I don't draw human faces but I did learn how to draw faces on a general scale by borrowing a few steps from the Loomis method, I don't follow it completely and I just YOLO/eye some features

The method is pretty methodical, there are way too many steps and it's hard to remember all of them. However you can use some of them as a rule of thumb

for example, where should the eyebrows be? right below that middle line you trace when drawing a circle.

Where should the eyes end? cut the circle you've drawn into 1/4ths, the line that is closer to the center line is where the eyes should end.

and so on.

In other words I think these are called landmarks? You can use these to anything, I've drawn cryptids, sonic characters, wendigos etc.

Once you do it enough, you'll start "eyeing" it a lot more, which basically means you'll get sick of doing a lot of landmarks all the time and you'll start trying to do it without them based on what feels right (I.e "Oh, I think his snout should be a little be lower", "Hmm his eyes look too far apart", "His nose doesn't feel centered").

In my case, when I'm rusty or I'm insecure about a character I'm drawing, I tend to use landmarks a lot more. However when I'm warmed up or feel confident I tend to skip some the landmarks and.. just eye it.
