Help on defining flat-looking corners

[Lucid]

Hi vray community.
I've been doing little renders to try and learn and improve, and I'm sorta stuck on how to improve this little bit.


The wooden corners and joints look pretty flat and dull(main concern as this is a WIP).
I've been observing other renders, but I can't seem to figure out how they have some sort of soft, dark underline on their edges/corners.

Any tips to improve this bit?

Thanks.
