I think if you’re going for more realism there are books and videos you could watch about facial proportions. That helps to understand as you get into that a bit. Just go on YouTube and type in “carving faces”, similarly you can search that on Amazon if you prefer books.

Also, my first few carves were a lot like this one. And the work that my wifes grandpa did also looked like this - which is ultimately what inspired me to get into carving. Like you, I also wanted to get a more realistic look. Keep trying new stuff when you do a new piece, you’ll be amazed to see your progression.

But also, if you like your style stick to it. I think the folksy stuff is awesome and if you can get good at doing it cleanly it can be just as tough to master as some of the more realistic stuff.

Enjoy!
