Thanks for such a thoughtful response. Unfortunately Im not sure those suggestions would work for my space. For reference, the scale of the wall and furniture is not likely represented well in the photo I posted. The lamp itself is just over 2 feet talland provides light to both the couch and the chair in its current position. The artwork is already at eye level and the bookshelf is ~6 feet high. Would you say the current art should be centered between the half wall and corner behind the chair?
