I am happy to custom make any panels you need. I can forward a colour swatch to match to the walls/decor...in fact invite your wife to do this and she may buy in to the project as she obviously will have better taste than you (I had to put that in case your dear lady wife reads this )
A few slender corner bass traps plus a few side panels for the walls (first points of reflection) and a rear absorbant panel would be a minimum in your room as a guess, but you obviously will know what's needed as you've already treated the room. Your wife may insist on the fugly foam things going, you never know! Don't forget you can get the side panels air-brushed with artwork or overlay photos done on canvas (simply stick them onto the panels applying spray adhesive to the corners) by sending off you favourite photos to an on-line photo printers.
