What does the word 'modern' mean to you? Can you say more about that? It is a pretty non-specific term.

Why did you choose to have your desk and screens in the corner instead of in between the two windows on the long wall? Does it have something to do with light from the windows and being on zoom meetings?

Having only one wall painted looks silly. Do you like that color enough to paint the whole room? If not, perhaps a lighter shade of the same color. Get a rug that looks right with the curtains and paint color, unless you are seeking different window treatments and colors.

So this is the living room and you are converting its use to an office? This square footage is possibly way more than you require. Don't you have a spare bedroom that could be used for this function?

no, this is the space on top of the sunroom(downstairs) and I was thinking to convert to office room...right now I have a laptop and table to work from home. I just need ideas to decorate, put some good furniture so that this space looks appealing.. Please note that this is next to our master bedroom.

Also I dont need any suggestion on paint...
