Where to move in 3D?

Question

3D

Hello! I know these are stupid questions, but still.
Started learning blender. I learned how to make all sorts of simple low-poly scenes like https://vk.cc/a7RR31 without any hints (I did it from the reference - the final render of the tutorial).
Got stuck. In which direction to move on? In principle, I can do similar scenes in the future, and I like them so far, but for the future I don’t think that this is the right vector of development.
As I understand it, it makes sense to go further into realism? Trying to make highly polygonal objects, scenes, etc. As I understand it, these scenes will take disproportionately more time.
Another main question - I would like to develop further, most likely in the creation of characters. But this direction is completely different from what I'm doing now. In this regard, you need to apparently switch to zbrush, because what's the point of trying to sculpt in a blender? Or is sculpting in blender not so bad and you can start with it?
It's just that the eyes run wide from the directions in which one can develop, and this causes a stupor.
Thanks

Answer 1

Change the direction - the optimal working tool changes.
This is logical!

Answer 2

3D does not end with modeling, or are you only interested in it?
Even if only it is high-poly, you also need to be able to, even if low-poly models are used in the project, then normal maps for them are built according to high-poly ones.
Well, besides modeling - working with materials and textures, which is also tied to light.
There is also animation (not only rigging and mocap, but also simulation of all kinds of interactions, scenes rarely remain static).
So there are a lot of development options not only regarding what models you are going to make, or it was necessary to clarify that you are only interested in modeling, if so, then ZBrush is a very useful tool for this, although you can do something similar with a blender, but the zebra has more options.
