Your drapes look like they're fine. It's hard to see if they're long enough--do they just touch the floor? That would be the right length. Make sure the paint you pick blends with the color of the drapes and the two chairs. The Edgecomb Gray looks like it would work or you could go with an entirely different color and add pictures and rug to pull it all together. Love the color Sea Salt by SW.

Hi, Don't you think your query is very open ended. There are thousands of color options available. Ideally you should look at few pics that suits your choice and then get a feedback on those for final color palette selection. Thanks, Nitin Cornerstone Designs, Bangalore

Why would you not want to use glass in those tall openings? It may be the main source of light for the interior of the building during the day. Unless you really can't bear so much sunlight or you are concerned about the lack of privacy at night. In which case you can use frosted glass instead of clear upto the top of the second slab level. Above that level you will get three vertical rectangular frames. You could commission stained glass panels for those. Alternatively, below the stained glass panels you could used wooden slats with gaps in between
