Thank you both for encouraging words.
@Chris: I agree with you, but in my test renders the sun ware higher, which illuminated the toilet seat in a way I didn't like

Also with lower sun, the curtains shadows come more into account.
@mib2berlin: I did put some plants outside on the fence, but it looks that my 1Gb card didn't like them. The render didn't start.
Is there any log file or alert too see when you hit the limit of gpu memory?
Best regards
Peter
