Spellbinding scene! Very peaceful and dramatic. There's a tale waiting to be told her of this unknown ranger/warrior at this ancient crossroads riding through the dense forest.
Especially love the depths you've created in the scene, using alternating bright-light and shadows. Love those ancient obelisk (waypoint markers), the waterfall, the colors (perfect!), the horse & rider, and the diffused waterfall/rivulet, and certainly the most detailed & layered trees, grasses and shrubbery.
