The coke is another of Julian Beever's work. I have already published two of his works here. The right artist I still do not know the name and found her at The Writing is on the Wall a blog about chalk art and they have some tips for those who want to start this art.
This is Sandro Botticelli's Birth of Venus' detail.
You can see the picture she is using as a model at the photo.
It's amazing!
