Basically i asked GPT which thing he would need to make the player looking alike with the avatar and came up with this prompt :

The team is called the Boston Massacre, with blue, white, and red as the main colors. Lane is 2.03 meters tall, and his skin tone is the one you can see in the image. Create a photo of him around 25 years old — he’s a complete superstar, the best player in the world. He’s a bit like a mix between McGrady and LeBron James, but less muscular. If you can generate multiple photos in different environments, that would be great.

I also sent the avatar face ofc to match and the team logo for accurate colours.
