Generate a highly detailed and photorealistic image of a charismatic street musician actively performing with an acoustic guitar in a bustling, historic European plaza. The musician's open guitar case should be prominently placed on the cobblestone ground in front of them, containing a visible scattering of various coins and a few small banknotes as tips. The plaza should feature picturesque historic architecture, potted flowers, and be illuminated by the warm, golden light of a late afternoon sun. Frame the scene using a medium shot with a slightly low-angle perspective, emphasizing the musician's engaging presence and the rich textures of the European setting.
