Is it possible to place the sectional where the chairs are now and place the chairs in the bay window area? If if is, I would try that for a week to see if you like it. I find sometimes it takes a few days to get used to new arrangements.

I had it arrange it like that for 2 years and now i am tired of seeing that

The sectional is a problem. Canyou replace it with a sofa?

No , cabt replace it

I think small additions like a tall plant in the corner, a floor lamp for warmth and a small rug to anchor the space can help balance everything, an end table between the chairs also adds function and flow. I shared some budget-friendly home decor tips https://dealsanddelights.com/ hope it helps
