Hi. I think you seriously need a local professional to help you with this, but for the meanwhile, I'd like to check what you mean by "first floor". Where I live, I call the floor that is level with the ground the "ground floor" and the next one up is the "first floor". In the US, I think, the floor which is level with the ground is called the "first floor" and the next one up is the "second floor". It might help if you reposted the floor plans marking your floors with an X so that anyone on Houzz who might be able to help you will be sure of what you are talking about. Good luck!

The sheer curtains looks good. The thick curtains can be changed into a plain one (neutral grey maybe) instead of a patterned one as it looks crowded. The tv can be wall mounted. Remove the decorative items kept on the tv unit. Reposition the black loveseat to near the sofa at an angled position. The cushions on the sofa needs some colors. Maybe you can match the colour of the cushions/throws to a painting . Painting can be hung on the wall above the sofa.

I would like to give you more suggestions to improve your living room ambience . The highlight wall in pink can be switched to some other striking color such as a teal blue or moss green color , then you can change the curtain to from sheer/transparent to a thick fabric and the color to a neutral tone such as white / beige /grey .And yes definitely adding more lights to the space will amp it up .. Hope it helps!

Shailashree, It's better to have pooja unit in the east direction! Having a partition is a good idea! You can even push the dining to the left wall and have the pooja unit near the closed kitchen wall! We can give a perfect solution if you could a better plan with kitchen updates and North point! Hope this helped you!
