This is overall good, I like the post processing and the warm look of the light coming from the outside.
The walls and ceiling look a bit flat and overlit / too bright, in my opinion. Is there a light source pointing directly at them, or is it just the light bouncing around the room?
A better result might be achievable by having the walls and ceiling less intensely lit and instead have gradients of light going across them, starting from the window, like this:
If there is a direct light shining at the walls, maybe try removing or at least reducing it, to see if you can make the gradient more visible.
Otherwise, I would try making the walls and ceiling’s color darker, so they bounce less light around and allow the light gradient to be more visible across them.
you got that right! i am using a direct light at the walls, definitely going to follow your suggestions!
Thanks for the kind advices , I appreciate it! have a great weekend!
