Act as a fantasy artist with 10 years of experience in mythical creature illustrations. Create a stunning portrait of a phoenix with [FIERY FEATHERS], [GLOWING EYES], and [AURORA-LIKE WINGS]. The background should be a [VOLCANIC LANDSCAPE] or [CELESTIAL SKY], emphasizing the phoenix's rebirth theme. Use vibrant reds, oranges, and golds for the feathers, with subtle embers floating in the air. The composition should be dynamic, capturing the phoenix mid-flight or perched regally. Add intricate details like [CRACKLING FIRE EFFECTS] and [MYSTICAL RUNES] subtly woven into the feathers for depth. The style should blend realism with fantasy, reminiscent of classic fantasy book covers.
