so I did a bad 'red' line, I hope it helps
for the horse, the mane a bit poofier, knees not so prominent,for the eyes, make the pupil a little tiny bit bigger.
cat;; head a bit flatter and ears shorter, the paw pads should look like little beans and be a bit more pointed. Pupils should be rounder. other than that, it's great
dog;; the ears are fine, though eyes should be farther apart. paws should e a bit more pointed, everything else is very good
