Too much blue...try removing the blue curtains. I love your rug! You need end tables with lamps just in case you want to see! It's quite dark in there. Lower your picture over the couch so that the bottom of the picture is 5" above the back of the sofa. It might be a bit small for your space, do you have others you could group with it?

This is a tough one without re-doing the floors. Could you call a tile store? Maybe they have some type of treatment to 'rough up' the tiles. Also, since you have elders in the home, grab bars placed in well thought out locations might be a good idea anyway, along with skid-free rugs.

coming to the dining area..yes id say you remove the seating entirely and concentrate on a foyer area since you already have space for a drawing room on the floor.. id suggest erecting a glass and marble wall in line with the wall that runs between the pooja room and the bedroom..say a bit of marble-glass-marble-glass-marble.in this case you have a small foyer area demarcated by this wall feature.you can deck it up by placing a nice console table in front of the central marble wall with a nice mirror to reflect the space and make it look larger or a sculpture with beautiful bracket lights on either side to accentuate the same.and on the backside of this wall you could have a crockery unit with a huge painting or a cluster of family snaps above it. if you could brief me a little on the look you're adapting for your house i could suggest some more treatments for the walls.if you want to avoid using too much marble you could also opt for a marble wood and glass look where you could take out some concealed storage for shoes etc. regarding the drawing room - what about a huge 4 seater in the center instead of 2 - two seaters with a table in the middle as in the plan..if you remove the central coffee table maybe you could replace the single seater with a chaise for 2 and also replace the 2 center tables with a nice long table in the center with an area rug running below it..if you could help me with the room dimensions maybe we could add 2 pouffes in front of the 4 seater so it creates more seating and doesnt obstruct the view if you plan to put a TV on the wall. what look do you have in mind for your terrace garden ? something zen or a little rustic toeing on the lines of the contemporary ? sorry for the late reply as i was travelling.. hope this helps! :)
