I think the only properly drawn horse was estella's old horse from her guarding duties but it was only one scene and copy pasted. Everything else looked like it was predrawn by a computer. I forgot what you call it.
I have nightmares about that horse… (⊙…⊙ ) i’m just enjoying a nice picnic in a beautiful field filled with flowers and then a huge ass terrifying horse comes and chomps on my big ass head ╥﹏╥
I laughed a bit too hard at this
The horses are all cg, they're 3d models the artists for manhwa often use so they won't have to draw them from scratch. Though they could get the proportions and the pose from the 3d model and then use a reference and redraw the thing so it looks like an actual horse instead of this demonic looking imitation. But that would take a lot more time and effort and they're already busy enough with just the art for the characters.
Why do all horses in webcomics have to look so fucking terrifying? Have any of the artists ever seen a horse? The rest of the art is so nice, but then you see that horse's horrifying face...
