Yes, to me that doesn't look like a steep cliff (though I can tell that's what you're aiming for), but rather, a hill. It's not the detailing, but that the design you chose is visible from all the angles, and never overhung by something. If those trees are supposed to actually be "moss at the bottom of a ravine" then you did miss the directional cue but the fallen rocks tell me that no, that is higher. Anyway, it would be cleared up at the table by a player asking "is this up or down" and you'd say "it's up, you can reach it if you jump but it'll take you a turn to climb up to high ground" and then it's canon and their imaginations will fill in the gaps.
