Ancient Oak Tree in Misty Forest Valley with Ethereal Lighting

Gnarled oak positioned centrally dominates verdant valley floor, trunk and spreading boughs rendered with intricate bark texture. Luminous yellow-green foliage filters sunlight from above, creating atmospheric depth. Misty canyon walls recede into background; white birds scattered mid-distance. Grass and moss carpet ground plane; rocks punctuate composition. Backlighting creates volumetric god rays through canopy, establishing serene, primordial forest environment. Digital rendering employs warm-cool tonal contrast.
