After struggling with horse anatomy from photos, I finally decided to search for white horses, figuring that I would be able to see details more easily than on darker photos. It worked out well, the details were much more discernible.
The last drawing I actually spent a hot minute on, would like to do that more often! Used a brush with ink and Deleter Manga screen tones, then messed with in Photoshop! Year of the Pig, baby!
