I think you are well on your way to a fantastic design. Reupholstering your dining room chairs is a great way to update the look and feel of a room. Perhaps a modern fabric that pulls out some of that great new grey color on the walls! Also, a rug would help anchor the table nicely. Happy decorating!

Hi mcamf -- I agree with Timeless about the drapes -- check out the example I gave to another homeowner with a similar window treatment:

If yours come out and up to just skim the floor rather than puddle it will look more polished. I also would update your chandelier as it's incongruent with your drapery rods. They don't need to match, but they have no continuity.

That said, this is a lovely room so far! The windows are large, so I wouldn't go big or bold with art, but it could use a little something. Either sepia tones to reference the furniture framed in silver to reflect your range of greys, or the reverse -- b&w or pen and ink framed in your wood tones.

Do you have any suggestions/ideas for the chandelier?

I would suggest a drum chandelier to update the room a bit. I assume with the grey paint you are going a little more transitional than the traditional dining furniture and I think a more sleek light will help. Here's an idea - lamps plus has a large selection at many price points.

I think a clear glass chandelier would be stunning! They can be quite expensive, but I did find this one by Kichler on ebay for $200 (or make offer). Just change out the bulbs and use dark grey shades. http://www.ebay.com/itm/Kichler-Lighting-Polished-Chrome-Finish-Chandelier-Clear-Glass-Transitional-/271955726273?hash=item3f51d30fc1:g:mLUAAOSwjVVVy3wl

Painting your walls off white below the chair rail would tie in your upholstery (cheaper than reupholstering!). Add white boxes for balance and architectural interest.
