I am looking for wall art /artwork suggestions that would go behind for sectional sofa for my living room.

As you can tell in the living room we went for a relatively monochromic look with a heavy emphasis on grey and black, outside wood accent wall.

We are in two minds, one is to have some black & white photography mounted something along these lines (https://imgur.com/a/U0JXtpN) or to add some colour to the space, potentially some abstract art with pop.

I am leaning towards the former but would welcome suggestions. Our design ethos is we like clean lines and attempting to keep a contemporary look. I am in Canada for the record.

Would welcome suggestions.
