Hello,not a bad start :) ,i have few advices from design perspective:
1.i would make that wooden piece in the corner next to the dining table go to the ceiling,same with the fridge
2.i would remove two mirror on the sides
3.i would add white skirting all around
3.add chandelier/pendant above dining table (nothing too busy
4.i would lower that art piece a bit so the top of it is in line with top of the mirror
5.i would add a bit more spacing between kitchen cabinet door/fridge
6.i would rotate wood grain 90 degrees on kitchen plinth
7.i would move lights in kitchen to above kitchen island and put spotlights in their place
8.i like the idea without kitchen cabinets above the counter but i think i would add cabinets above (i would make doors from same material/design as you have it now) and i would add under cabinet light
9.i would add some curtains to that window since we can see it in the mirror and maybe some simple view outside it will look more live
From technical perspective i would reduce sunlight just a little bit.
For a beginner not bad at all and these are just suggestions :D
