In the following image, i had to create the sand ground where the bottles were laid into. Making sand at such high resolution is not that simple, as it demands a lot of detail, so i had to first create a good model of the ground, made in zbrush, with small waves from water as well as all little holes and dents that sand has. We do have a transition from wet sand to not so wet sand, from bottom to top and that helps to give a more realistic look to the image.
Attention to details was also given in the bottles - there are small light scratches and layered dust, which had to be removed a lot as the client wanted the phones to be as clearer as possible. Also the corks were given a bit of detail just to improve realism.
A final retouch to add little shells and that was that.
