Redecorating what? table? windows?

I love your eclectic style. You might consider this crystal embellished orb fixture from Troy Lighting for just the right touch of formality.

For now, I need a new chandelier that wil go with the existing furniture.

It's a bit tricky, because your room is contemporary, yet traditional. The fabric and glass table top make a modern statement. Check out this drum dining lamp. I think it offers the "today" vibe you like, while respecting the style of the chairs and buffet.

I think a nice simple drum with a shade the background color of the chair and window fabrics would be very nice.

Definitely a drum shade with a little bling to pull the room together, Nicely done so far, just need new lighting.

Have you thought about Porcelain?
