I don't see that as the problem.... The photograph lack depth and it's plain DULL....
Life cannot be serious all the time and to me Photography is a kind of relaxation. So being a little bit mad is fun.
The bakery is beautiful. I have a few more pictures taken there. I posted that when I saw the table slightly twisted and of course the lack of subject. The food was what I was aiming for.
Hope I have not offended anyone.
You haven't offended anyone, we are the one's who might offend which is why I'm always reluctant to offer criticism, but hopefully any criticisms are constructive and taken as such.
Something like this??....Personally, I'd try take this from a lower angle, without faces obscured, at a lower f stop, starting closer to the people so that the corner of the table isn't in view. I'd also see how it looked making the diagonal more diagonal.
