I agree with you on that! I have a postcard with the royal family and it's sepia if I'm not mistaken. Wanted to post it but could not find it.
Sepia always works when it's about something old and also works on buildings. You can't go wrong with a sepia or monochrome building. You'll learn, don't worry and besides, there's no right or wrong as we are not the same, each of us has different preferences. 🙂
Thank you for your support and have a nice day 😊
