Using this exact image as reference, keep everything completely unchanged — the woman, her pose, face, hair, black lace dress, jewelry, the cake with "30" candles, the table, the balloon arch at the top, the fairy lights, and the confetti sprinkles in the air.
The only change: remove the hanging triangular flag/tassel garland (the gold, cream and blush pink triangular pennants hanging on a string) positioned below the balloons on both sides of the frame. Replace that area with the same plain wall background and warm lighting seen elsewhere in the image, keeping the fairy lights and falling confetti pieces intact.
Do not change anything else — the woman, dress, jewelry, cake, table, balloon arch, and overall lighting must remain exactly as they are.
