Rendering and lighting help for novice Blenderer

I would like for someone to please review my blender file. I’m trying to copy the same looks as the attached graphic. Im looking to have a nice render but not something that will not take days. I guess I’m trying to find a good balance in quality.

If you go for the looks in image and want “something that will not take a days” i do not quite get your use of Glossy material or Cycles chosen as a render engine either.
