I am bothered by the diverging verticals. Also, the addition of objects in the lower left hand corner is not helpful. I would recommend, that shoud you have the opotunity to do so that you return to this scene. That you use a tripod. That you make a that has as its top boundary the cross piece of wood above the three squares. The bottom of the image should be located somewhat below the pot and the right and left hand margins be at the edge of the outer arch edge. I would recommend that that camera be moved to the left...relative to this image and put into a plumb position with the camera back parallel to the back wall. A reflector may also be a good idea.
This image is one that a lot of us might walk away from. It is a tough shoot, it is hard to get curtains or drapes to hang perfectly vertical even with a tripod. The light level is aparently very low and the camera is without any perspective controls. Frankly I would agree with Claire S's idea if reshooting if possible, but I must say that under the conditions at the time it is a very good effort and I have enjoyed the image.
Again this is one of your shots a LF camera would have made this a great shot. but 35mm doesn't allow the control so your hightlights are burned out and don't help the pic
Well... call me wacky, but I kinda like it! I think those burned out highlights give it a sort of 'mystical' feel... yeah, I do wish there was more on the right & less on the left, though.
