by the way, the color is BM Revere Pewter and we'd eventually like to change the chandelier. I'm thinking I'd like to lean towards a yellow for the drapes...

The placement of the window calls for something very dramatic What about a textured metal valance with a softer drape

Something like these





move the cabinet from the window .

the room is narrow, so you want to bring in more bright and vibrant color ( yellow-ish ; golden). and bring the drapery almost to the edge of the wall to give you D/R a wide appearance . i would go with Asian inspired look and curtains, your floor and the furniture is absolutely beautiful.

Or you could introduce a more dramatic look in his room by wallpapering the top portion of the walls
with this and purchasing drapes in light grey

Istlady86, have a look at the tonicliving.com website. They sell curtain fabrics and will custom sew the curtains for you. I don't think it's horribly expensive.

I can see either of the two patterns below bringing some pattern and life to your already lovely room, but they have lots more to choose from.

I can see a couple of pieces of art side by side going on that wall on the left. Abstract would look great in here - will keep it looking fresh and modern!

the second print is very interesting, karemore55
Nice!

@ann dee, I love this website, even though I haven't actually ordered anything from them. They get featured in Canadian House & Home often. Their patterns are very on-trend.
