|Greetings from the Critique Club
Technically this is a good shot, not blown out anywhere etc. The composition is also good, and if it was a different challenge topic, I am certain it would have received higher scores. However, I believe there is only really a tenuous relationship between the photo and the challenge topic. Yes, it does have furniture in it, but is the furniture the main subject of the image, well, I don't really think so. Seems a bit of a shoehorn entry and I can't help feeling this is why you received a sub five score.
As I said, I think if you had this in a different challenge, then it may have scored better.
