Vision: This forest looks like really misty (& mystic). The fore-plan's well-rendered, and the backward's fogged. Looks like you entering something very mysterious.
Originality: This' not a rare theme, but it's made very well. Looks like a professional artwork.
Technique: Again, the forward's rendered detailly, all the plants & leaves seen good. And, to the depth of the picture, it slowly dips to the fog. This creates sense of a presence of somethin' mysterious. A color gamma's strictly green, black and white. Not many colours, but it don't bothers. Otherwise, it's used just right & fits to main conception. Just one: trees to the left looks skewy. I think it because a retinar's too little, or focused on far object.
Impact: A very well work, concept & tech. Quite a talent.
