A cinematic photorealistic scene inside a magnificent fictional Glööckler School salon. Two teenage boys practice a formal but natural greeting under the guidance of an etiquette instructor. Both wear magnificent white ruffled shirts with abundant layered chest ruffles, ornate ruffled button plackets and dramatic ruffled cuffs, luxurious velvet bow ties and tailored velvet blazers. Their hairstyles are immaculate strict undercuts with perfectly clean sides and backs and razor-sharp defined side parts. The instructor gently corrects their posture while the boys practice smiling, making eye contact and greeting each other respectfully. A huge gilded mirror behind them allows them to observe their own posture. Warm, sophisticated, encouraging atmosphere, photorealistic European fashion-academy photography.
