I think a comfortable distance between the island and the counter is around 42". It seems that you have only 30" between your cook top and the counter. I might be a little too tight. The wall between the entrance and the kitchen could be 4' long instead of 6', you would then be able to move the island a foot which would give you more room between the cook top and the island. Could you switch the location of the toilet and vanity in your dad's bathroom so your enter facing a vanity instead of a toilet which is a lot nicer.

You can mirror sofas group . And place large tv on the wall center aligned. You can see it from dinning and living area

Let your wooden beam be as it is. put your Led lights in the other direction ( two on each side in one rectangle , so the total will be 16 units of say 10 watt each Led.), as to balance the horizontal and vertical shape. Don't put anything on the wooden beam to retain its the beauty.

Hi Raghvendra! What I understand is that you require ideas for cushions and also for the wall. First of all, decide on the theme which you are going for.....modern...European....etc. Your furniture looks a mix of the two. As such a full view of the room would help one to decide on the best combination. Also the furniture material esp sofa will decide the texture of the walls and the cloth you will use for cushions. Also the size of cushion will matter. Personal choice of the color is best. I always go for rustic looks which matches most & mingles with all set ups. It give a look of luxury too. Pl consider all these facts before you decide. Hope this will help you. Looking forward for a happy home!!
