Painterly style workflow

I’ve bought the program just yesterday and was wondering how could I go about painting a 3d object with just some solid colors and a soft brush for shading, no PBR material whatsoever? I tried shading with the basic brush but I don’t know it there is a software problem (I have to mention that I’m running on latest version of mint with a huion graphic tablet) or the brushes works different that I was expecting, since I’m used to paint în either Blender (which I hate doing) or Krita (which I love doing).
