A majestic Celtic forest guardian with antlers woven from ancient golden oak branches and flowing auburn hair moving like wind through leaves, emerging from a misty enchanted Celtic forest at golden sunrise, expressive wise emerald eyes with detailed white light reflections through canopy, cel-shaded with bold black outlines, dynamic upward composition from below looking through ancient trees, deep forest green and warm golden amber palette with soft misty wisps, powerful ancient mood, scattered glowing firefly particles and floating mist droplets, Celtic mythology nature spirit concept art with soft bokeh of distant stone circle ruins
