After some months of work it is finally done. It was a simple idea - a coffee break. I wanted to make as photorealistic as possible. I am quit happy with the result. But of course I see things that I could not manage totally. All the models are made by my self. I worked with Blender 2.81 and Blender 2.82 and it is rendered with Cycles. I looking forward to your comments.
Here are also some test renders I made for every object.
