Using this exact image as reference, keep everything identical — the woman, her pose, face, hair, black dress, necklace, the cake with "30" candles, the table, and the overall lighting/composition — but completely replace the wall decoration behind her. Remove the pine/fir garland entirely — no Christmas tree branches, no pine needles, no New Year decor of any kind.
Instead, decorate the plain wall with a warm birthday party atmosphere: soft warm string lights (fairy lights) draped across the wall, paired with elegant paper or foil balloon garlands in gold, blush pink and cream tones, and a few hanging paper tassels or small metallic confetti details. Tint the overall wall lighting with a warm golden-amber glow, moody and low-key rather than bright — cozy festive birthday atmosphere, not overexposed.
Keep the woman's pose, face, outfit, and the cake completely unchanged. Only change the wall decoration and its color/lighting tone.
