Maybe you can post some photos of the room later so we can see. When you get to the wall art part of your makeover feel free to check out my store. http://andee-photography.artistwebsites.com/galleries.html ~Andee~

I strongly second One Plan's idea about looking for another architect. If this one is not motivated, all the fame in the world is not going to help. An alternative approach to finding an architect is to find some good contractors who have built things you like. Ask them for architects' names. Make sure they work in your price range. In the meantime, you can find out from your local building department what the set back and height restrictions are. Are you required to build parking areas or garage space, what kind of airspace restrictions do you have for neighbors' views and sunlight, that kind of thing. Often this stuff is on city websites or handouts at the office.

I agree with divadeva. More lights. If you can add pot lights do it. If they're already there add task lighting and up the wattage on the bulbs on the pot lights (replace with LED and you can make them brighter because the wattage on LED is lower for brighter light). If you have all of that add decorative lighting. If ventilation is an issue find a way to move the air around or add air filtration. Maybe the HVAC is deficient. Maybe you can add a HEPA filter instead of the standard one that comes with the unit. Call an HVAC specialist to see if there is a way to boost air flow in the room.
