The lighting doesn't look as soft and natural as the first picture. Lighting has always been that hurdle I can't jump across, but now it's starting to become more of an issue. Right now I am just using two emission planes for the light source.
The reference image is a studio lit still life. There are two "Soft Boxes" camera left and a spot light on the background. Probably a black card camera right to prevent light from filling in the shadows. It appears a relatively long lens was used to compress the scene and emphasize the shallow depth of field.
Here is how I recreated the scene in Blender with a camera focal length of 150mm.
