For a first project this is quite good !
Model and texture work is clean, now you can push the render further by adjusting lights and materials !
About light :
The overall lighting is a bit flat, there could be a bit more shadows, contrast, and especially more reflections .
-Start by setting off all the light, grab a nice HDRI from here : https://hdrihaven.com/hdris/
if you don’t know how to setup the HDRI look at this : https://www.youtube.com/watch?v=jqOXEQWRY4A
This will add some colored lighting and also interesting patterns in the reflections, making the scene more alive.
Then, you can keep it like this, or lower the HDRI a bit and bring back some lights, one after the other. Or you can start fresh with a spot lamp and try to get the maximum out of it, it will be your primary light . You can then add some secondary lights but try to keep them with a lower intensity than the primary (or said differently, they should contribute less to the overall lighting) . By judging the reflections, you have 3 lights that have nearly the same intensities around your subject, this is why it look evenly lit, but also is a bit flat.
Now for the materials :
(you can tweak materials and lighting all together, generally you do a back and forth until it looks right).
There are a few issues :
-The plate can have more reflections, if it’s not made of paper then try to lower the roughness .
The white of the egg seem to have a good roughness value, it will show up better with the HDRI.
One thing you can do also, is to grab a wood texture for the floor / table , like this one : https://texturehaven.com/tex/?c=wood&t=green_rough_planks
That will just put more context to the image, but it’s optional depending on your taste.
Despite all these comments, you have a nice basis, models are clean and composition is good, and the overall image kind of work. Now every little improvement will push the render further !
Good work !!
