A few words that caught my eye from the brief were-
1. Immersive - an illusory environment that completely surrounds you such that you feel that you are inside it.
2. Antique - having a high value because of age and quality.
3. Luxury - a state of great comfort or elegance, especially when involving great expense.
i tried to bring the look and feel of my design as close as i could to these words by the application of gold and silver text for luxury and making the image look old and worn out for antique. Immersive was the difficult part. For immersive i brought down the allover brightness of the image and after that started to add the brightness back into some of the areas to create a visual hierarchy in such a way that, a viewers eye will first land on the face of my subject and stop there for a while, after that his gaze will move to the shoulder of my subject (being with the most exposure), and then leading to the rest of the dress slowly.
