When I look I this, I’m wondering what’s supposed to be the focus? What is the purpose? What is it trying to show?
My eye feels pulled to the left, but it’s largely “blank” and plain there – Seems unimportant for something taking up about 1/3 of the left side (which is why my eye is drifting there). With nothing over there, that should just barely even be a part of the image (like less than 1/8 if at all). That object (painting? Wood? Not sure what it is?) in the back seems like it should be important, but my eye doesn’t feel drawn to it. With that plant on the edge, I’m almost curious as to what is over there (especially with the “boring” left half). So if that object in the back is the point and focal element, make it more important in the image by bringing it closer to the camera. You could also use the Thirds or Golden composition guide to help with the composition.
What I’m trying to say is that the composition is struggling. Figure out what is important and find ways to bring attention to it by making it closer, have lines and lighting lead toward it, and reducing the unneeded clutter or distractions.
As for if anything else should be in the scene… Who uses this space? Male? Female? Single? Married? Kids? Hobbies or interest? The more of these kinds of questions and details you can figure out (even if you don’t show it in the scene) the more you can get a feel for what should (and should not) be there. Just make sure that anything you add doesn’t distract from what you decide is the focal point of the image.
