I don't think your floor drawings attached, but let's get this started. First of all, coastal India means you have fabulous elements to draw from and you can use lots of color successfully! Pull together a palette that will give some continuity to the entire space. For example, include a blue that is found in each room (enough to notice). And when mixing patterns and textures, take a good look at them together before purchasing to be sure there's some flow. NOTHING needs to match, but they all need to get along.

I like second plan! That space will fit the wardrobe perfectly. Take all colors from the art. The colors can be lighter or darker than the colors you see in art. Take "Venice" with you to paint store and they might be able to help you choose good colors. Idea: paint four walls the same and see if you like that. If you feel the room lacks interest, then paint the accent wall. Choose a pale green that harmonizes with "Venice" and a darker green accent. Yellow + red accent White + blue accent

Vikrant, is the picture taken from the front of your Entry door? I love your style and pieces. Just a few suggestions if this is the view when you first step into the foyer, I am not an expert! Ganesh in the place of the mirror to greet you and your guests as Goddess Lakshmi is supposedly behind him, will create more prosperity to the household. A recessed focal light from the ceiling to highlight its beauty. Another silver empty frame placing behind Ganesh, similar to the mirror to frame the idol or a Rajasthani silver jali work piece that way the wall behind would not look empty either! The beautiful mirror can be placed where you have the Ganesh now, that way the positive energy coming into your house does not get bounced back or out...

Very interesting space and the exterior looks fabulous. My only critic is that I don't really love the kitchen layout. I feel like the peninsula cuts off the flow, but I understand the reason for wanting to have the cooking area on the peninsula facing the dining area. I feel if you were to get rid of the peninsula and add cabinetry on the blank long wall with the cooking area, you would be able to get more counter space for prep and additional storage. Perhaps you would also be able to incorporate a table island. You may need to relocated the sink onto the back wall to comfortably add an island/table. I'd play around with it a bit.
