Great job, here are some observations.
Look at the wall edge in your reference and compare it to your render - notice how the real edge has a slight bit of width to it, that is where there is some edging under the paint to protect the corner from damage, it creates a little raised bump on the very corner that catches specular light.
The saucers and cups need some oompf… try Orinoco’s suggestion, or perhaps the SSS material property.
Again, looking at the reference, the reflections are much more complex in the photo which makes sense, as one would assume there is a room full of furniture, equipment and people, all of which would contribute to the scene.
The wall needs some texture (there are visible brush marks in the photo)
Reflections on the counter top are too sharp and do not fall off over distance.
The shadows are totally black, try AO or add fill lighting to soften them.
Notice how the brass reflects colored light on the wall behind the machine in the reference?
I find the composition of the reference image more visually interesting, the machine there looks substantial and solid like the workhorse it is. In the render the machine looks skinny and is just part of the shot - put the focus on the machine, perhaps a different focal length would help.
Details for sure, but this could be really great! :eyebrowlift:
