Mystical Portrait of a Teenage Girl in Dark Fantasy Setting

Portrait of a teenage girl in a dark fantasy setting. She has long blonde hair tied in a ponytail, emerald green eyes, and pale skin. She wears tight, black flexible clothing with a hint of a mysterious atmosphere. On her right upper arm is a black thorny tattoo with a few small leaves, glowing faintly red in the center. Her expression is calm but focused, like someone hiding great power. The background is blurred shadows with faint hints of magical light. The tone is mystical, slightly ominous, yet beautiful.Her eyes are glowing blood red, and shadowy wisps surround her, as if she is about to vanish into them. A faint illusionary shimmer appears behind her.
