Right, so next up I'm going to show a bit of a step by step of my long irritating process in case anyone wants to either try or just find out how I do it. I'll be adding to this as a WIP as I continue creating the art itself so it finishes when I'm finished!
YOU WILL NEED:
Ibis Paint X or similar app
Photoshop or similar app
Your mighty fingers
A bit of sense on how lighting works

Step one:
Do some linearting, as long as the outline is good, don't worry about much else! I usually do my lineart on paper then take a picture and trace it on the app but you can just draw it on the app as well :)
Step two:
All powerful and dreaded bucketfill! Add a layer underneath your lineart. Make sure there's no gaps as you want it to stay inside your lines! Also, DONT use just any colour. Pick the grey right in the middle of black and white or at least as accurate to the middle as possible.
Extension: So hide your lineart real quick and check the silhouette. See all the ugly little lines? Go over those with the colour you used for bucket fill. This is where you might add hair details or refine the edges so it looks nice!
See! Much better!
(Insert image that looks better lol)
Step three: Make your lineart visible again and go into your brush settings. This is the brush I use, on low opacity. Ignore the size, I change the brushe's size all throughout! I also tend to change opacity depending on how much of a highlight/shadow I want or how sharp I want the shading.
Step 4:
Using the brush settings above, I begin adding in highlights. I use a grey only slightly lighter then the other one and practically cover the entire horse, leaving only the darkest areas untouched and just going over the lighter areas over and over again to lighten them. Remember your light source and how shadows work while drawing. I often forget my light source and have to redo the shadows.
Step 5: Start in on shadows as well as detailing the highlights more. Begin refining more detailed areas like the muzzle and around the eye. Switch your lineart layer on and off constantly, as you can use it as a reference for where shadows go but you want it to look good without the lineart on.
