An ultra-realistic group selfie.
The person at the center uses the uploaded reference image strictly to preserve the exact same face, identity, hairstyle, body proportions, and is wearing the exact same outfit from the uploaded image with no changes at all.
The subject is holding an iPhone, taking a casual group selfie.
Surrounding them are Chris Hemsworth as Thor, Gal Gadot as Wonder Woman, Scarlett Johansson as Black Widow, Mark Ruffalo as Hulk, Henry Cavill as Superman, and Robert Downey Jr. in full Iron Man armor. Everyone is standing close together, hugging, smiling, and posing naturally like close friends.
The mood is fun, joyful, and friendly. Bright daylight, cinematic yet natural lighting, realistic skin tones, candid selfie feeling, ultra-high detail, photorealistic quality.
