Create an image of a majestic dragon, intricately sculpted from pristine white marble, positioned in a dynamic pose as if rearing up to strike. The setting is a deep black background that enhances the stark contrast of the white marble. The dragon's tail is beginning to explode into a cascade of vibrant blue and green paint, which looks like it's bursting forth with great force. The paint transition should appear fluid and almost gaseous, symbolizing a sudden release from binding limitations into expansive freedom. The focus is on the detailed texture of the marble against the lively, fluid paint using bold colours of the rainbow to show the dragon exploding. --ar 16:9
