Very dynamic richly colored addition. Does it come larger? Cause a queen is going to cover a lot. I'd get pint matches from SW and continue the pattern all the way up the right wall. You can use poster paper also.

the wall is a fantastic idea! I was able to order the rug in a larger 8 x10 size. thank you!!

Don't worry about that fantastic rug being kiddish. I have seen similar in living rooms.

I'd let your son select the paint color and furniture. He clearly has great taste!

I'd like to see army green bed linens with this, wood headboard, bedside tables, new more modern looking fan.
