The positioning of this horse shows a good sense of positioning by your friend...more or less in the middle of a garden where children will like to hangout.

Moreover, the height of the horse, designed by the person who made it, without any climbing aid is not a good idea. I believe children will like to climb it.
Because children hardly give up when it comes to things like this, they will climb it by all means and eventually fall down as they wont be able to come down by themselves.
