If you are using LEDs always choose warm white for domestic interiors.

Hi Jayrees, I totally agree with what Kat had to offer, I would suggest a non geometric pattern on the rug as the floor is already geometric, a light colour and subtle pattern if you prefer a pattern. The mirror should definitely be moved and I would consider a large light print to compliment the new rug and and drapes. It's a pity that the window screen blocks the view (it's a nice view) but the heavy screen is a necessity these days, I would remove the stickers from the glass to help with the openness. Just noticed that you have an air con in the room so you may be able to remove the screen.

My household isn't too big on decorating our front-yard. However, we do embrace the festive season with indoor decor. I love these simple xmas setups which I found on Houzz – great for those with small spaces too. full project

I suggest printing off your plan and drawing your furniture on to scale. Allowing for at least a metre between things like the island and table, sofa etc , it will be hard to fit everything in. The room has a lot of doorways etc that need access space. You could perhaps have the dining table in front of the island and then a couch facing the island but is this enough seating? The other thing to consider is what dining seats you have and how much space they take up, both in and out from the table.
