Quite good for the beginning.
Suggestions:
maybe you find a better wood texture for the kitchen furniture.
Apply some mapping on the reflection, especially on that round table and the material of the worktop. Also on the chair.
Redo the baseboards... it looks too sharp and GC. Maybe think about a bit other material combinations in general (okay, that's personal subjective "taste"), but at the moment everything is kept in this creamy colors.
The stone material of the table top could be more calm...
Rounded edges on the walls... so they are not razor-sharp.
Maybe switch on the light in the middle, not on the left side, so the viewers´ focus gets guided to the center.
Table is a bit too big for such a small kitchen. A not so heavy design would fit better.
Between furniture and walls, in reality there is always an edge mould. You will never see such gaps in real kitchens. :)
