I am not sure if this project is over, But try zinc sheet it looks great and gives you an industrial look.

Dear Vinod, That's what happens when you give a project to a carpenter cause they view it as the single element and can't imagine where and how it is going on with the space around. "They literally don't care" except the money they save in that project. As the wardrobe is glossy and dark gray you have to make-over everything in that room to makle it look better. So better go for removing it which is more economical, and if your wardrobe is done with solid wood or timber just go for wood finish paints (veener/varnish/some other) or else go for duco paint or any other that can be applied on it. But BETTER consult a Designer or an Architect to those kind of works not carpenter or some vender. And lastly remove that funky looking overhead outcrop. Have a nice day

pooja room should be depicted as traditional and ethnic, one can use wooden carved MDF sheets for paneling with duco paint as its finish. other option can be wooden square mesh panel with bells - photo attached for reference. POP niches can be made in dome shape with led lights. niches in the wall, reference picture

I would suggest u to go with white sheer and light grey curtains only. If u want want to play with bright colours then it is safest if u add them in form of accessories or decors, reason one being the space is small n it’ll look more crowded then. It’s better if u avoid orange n yellow in this bedroom at least. If u can give a better picture of the accent wall colour here it would be better. Then u could go with a darker shade of it to form the colour scheme. White+Grey+Purplish brown. That’s it.
