Yeah, sure! It’s a whole bunch of slow building blocks. Start out with the base colors and values in an ebauche (a sketch layer comprised of approximate colors) Each consecutive layer, you will slowly move away from solvent and into your fats (drying liquids like liquin/galkyd and oils like linseed or walnut). Start to build your blending in the ebauche and go on top of it to smooth it out layer by layer. Once you get to the fine details, keep your layers very thin by using your oils
Use as pure of pigments of you can in your final layers (sometimes mixing in titanium white) to create a sense of luminance. Oil painting is a waiting game where you can develop and reshape layers very slowly if needed. Don’t be afraid of pure colors in the skin (alizarin, ultramarine, any cadmium, and more) skin is translucent and you can see where blood fills our face (like our cheeks) You can figure out someone’s skin temperature by looking at warm areas like the cheeks or lips, and cools
Cool tones are by the chin, and can exist in shadows, but not always. It depends on your light source mostly. Also save your paints in a stay-wet palette so you can reuse any colors you mix! Hopefully this helps a little! Feel free to ask about any specific part, and I can easily break it down <3
