I was thinking of wooden panelling on the side walls with vintage photo frames..will help in the acoustics of the room too

kitchen go for a bright baby pink or a red shade and go for cupboards that fit next to your kitchen counter cause maintainence for the walls is an issue. The bedrooms should be designed to your liking are you person who likes akcents or shades than option go for better metallic finishes with new emulsions.

Pista green color looks good. I was actually looking whether we can make something to contrast the blue glass windows.

the orange cladding...try something darker colour
