High end product retouching of skin care product photos

I have taken 4 basic product photos for a client and they want to photoshop them to elevate them to a more luxury and high ended images. Here is the brief from the client: "We were hoping for a luxurious, clean style. I like the reflection of the products, perhaps we could elevate the original images through lighting and reflection, see examples below (La Prairie photos). These are quite dark but we would like to have a bright, luminous look and feel but still making the products look high end as below. The gradient backgrounds and lighting of the products adds a sense of elegance and makes the product appear very high end. " Please find attached some of the source images (Luminous White) as well as the reference images (La Prairie) Since the brief is quite open ended I would appreciate if you could perhaps send through one sample first for me to send through to the client and if approved, you will be given the thumbs up for enhancing the remaining 3 photos. Please send through quotes/previous work if possible. Cheers, Geoff
