I love the first picture! It looks like the horse is really stretching to eat the plant. (I work around horses irl and they would do that.) Very realistic!
At least to me, yes. The mane hiding the neck and the slight step forward w/ the front leg make it look like the horse is trying to eat the plant. Something in the rider’s expression comes off as resigned, which is also accurate. It does depend on the horse, but I’ve had many do that to me when trying to walk them past tall grass. They’re always up for a snack… or two or three. They’re not picky.
