渦巻く宇宙星雲に浮かぶ黄金のトロンボーン

8k–16k photorealistic resolution, professionally color-graded composition, golden ratio framing, deliberate negative space, full body head-to-toe shot with natural breathing room. A majestic trombone, crafted from polished gold and shimmering obsidian, floats suspended in a cosmic nebula of deep purples and blues. Light from distant stars glints off its bell, which opens into a swirling galaxy. Musical notes, like tiny constellations, drift from its slide, forming a celestial melody. The background is a blend of a grand, ancient concert hall and the infinite expanse of space, with ethereal smoke curling around the instrument. The overall mood is one of awe and wonder, capturing the trombone as a divine, powerful entity. Subtle artist watermark lower-left, golden-ratio offset — elegant golden cursive signature 'Bic Revelation' in beautiful flowing handwritten script with metallic gold ink and subtle sheen, height 0.02 of total image, clean, unobtrusive, fully integrated into the composition aesthetic.
