Prompt: Design a multifunctional interior space for the reception lounge of a guesthouse, incorporating a reception desk, lounge area, and a bar space. Infuse the design with authentic Tibetan ethnic style while catering to the functional needs of each area. Utilize strategic lighting to highlight specific zones while preserving the ethnic ambiance. Employ earthy tones and traditional Tibetan ethnic colors for authenticity. Ensure a high-quality design output with attention to both ethnic motifs and functional coherence.

Negative: Exclude design elements that disrupt the functionality of the reception, lounge, or bar spaces. Avoid overly dominant lighting that detracts from the ethnic ambiance or compromises the functionality of the areas. Exclude design aspects that deviate significantly from the traditional Tibetan ethnic style or distort the functionality of the multifunctional space.
