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...

If you love that wallpaper, use it in bathroom. Not really right for behind bed. I would go a drum style chandelier. In a silk pale gold. Your bed looks zen or Asian to me. I love it. But, you don't. Need to much with it. Keep it simple a more formal drape on windows, color would depend on wall color and bedding. I'm thinking a dramatic peacock satin. Use a lighter same tone on walls a rich teal. Ceiling can be gold leaf. With alight that cast shadows on ceiling at night. Then your wall paper will tie in. Furn should be mirrored.

I'd suggest you have a look through the photos section on Houzz - or there's quite a few good articles on how to decorate :) maybe both you & your wife could save pictures to an ideabook with a few words on what it is you like about each one, and it'll give you more of an idea of what type of things you like? I think colour-wise, turquoise and peach can go together really well - maybe a warm cream colour on the walls & pops of turquoise and peach in the form of throw cushions etc.? Again, just searching on Houzz can give you some great ideas - just literally searching 'turquoise and peach' brings up quite a lot of pictures :) to get you started I've just picked out a few which I personally think work well :)

Bamboo roller blinds are an inexpensive fix. They can be cut to fit and have a decorative look.
