House floor plan - Where could I make improvements?

Sorry I had network problems

Thanks for the opinions I will make a fundamental revision and then upload it.
@Shism currently I have a ceiling height of 2.20 meters, which resulted from the renovation of an old building.

hello everyone, now I finally have a new draft for discussion

Hello, here I am again, I thank everyone who has shared their opinion with me so far, I have taken a lot to heart and made fundamental changes. @ Building expert, I also had the financing offered to me with 400K€ to be a bit more secure. Here are my new floor plans, maybe you can "bash me" again. Thanks to everyone in advance.

What did your architect say about your planning back then?

the floor plans again

Is there already air where it says DG / OG? If not, you are missing a window in one room in the DG. Why don't you put your utility room in the basement by the heating? Then you can put the kitchen in the OG and create an open cooking/living area.
