Dear Crazyjunglite, please let me add some ideas for your space. I beleive that a nice combination of two curtains like the one with the blue and peach double curtains in the picture, will give you an eclectic feeling that matches to your painting. The combination of colors that I suggest is this blue with brown flares and the cream-peach taffetas, and the soft cream sheer behind. It will join all the rest beautiful items suggested by now: https://www.etsy.com/listing/163787105/blue-curtain-polyester-fabric-122-inches?ref=shop_home_active https://www.etsy.com/listing/163785041/light-yellow-beige-curtain-polyester?ref=related-6 https://www.etsy.com/listing/167660815/35-discount-for-one-pair-of-two-beige?ref=listing-shop-header-1 https://www.etsy.com/listing/167363693/ecru-sheer-curtains-fabric-118-inches?ref=shop_home_active

If I am having trouble finding a rectangle glass top table I usually order the glass from a local (to the location of my Client) glass shop and then the base from one of my furniture vendors. a dark table with your light chairs should not feel dark given that it is in a room with what looks to be lots of light with the large glass door and side window. I do think the glass would be perfect for the area. What size table are you thinking will fit the best in the space and for your needs?

#1 is the only one that works with your doorways. But I would rethink the sectional pieces which look too large. You will need at least a floor lamp. Your table/chairs looks narrow in relation to your sectional - is it to scale in the drawing? You may not have enough room. I would use a sofa against the wall and two chairs on either end facing toward each other.

The recommended fit around a DR table is 24" larger on all sides for the chairs. You won't have that on the 6'8" side. I'm thinking the rug is going to be too small for the room 8x10 or even 9x12 would have been a better choice.
