I usually start with 1450 x 1700 but I have a habit on sketching on a small portion of it haha ;;. My lineart brush size is around 3 - 5 pixels depending.
You gotta consider the light direction first? I’m not the best at explaining but you should be able to find basic tutorials of lighting/shading which will do better at explaining than I will ;;. I’m still not the best at shading so theres obvious shading mistakes here and there if you look closely(ornot). Mainly I do my shading on the multiply layer and with a black overlay.
