Horse Vector Drawing

This was a sketch that I did about a month ago that I wanted to try to turn digital. I've always been fascinated by digital art, but I've also been drawing with pencil and paper my whole life and have already learned how to draw that way, so it feels awkward to draw with a mouse of finger on a tablet. I recently figured out that I can turn my drawn art digital by making each group of shadows into a shape with the bezier point tool thing on Adobe XD.
