First of all I would like to say that the South has it all over the rest of the country for great design and creating welcoming spaces people want to gather in. Some of the best examples of mixing old with new and creating exciting vibrant interiors is by Southern designers and homeowners. The wall color of your dining room is warm and unpredictable. You could enhance the wall color by painting the ceiling more of a cream color and keep the off white trim. The challenge I see is that the chair fabric looks weak next to the area rug. I would recover the seats in a bold taupe and off white stripe which would give the chairs a more crisp updated look and compliment the more contemporary animal print rug. Then I think the blue and white ginger jars would work. I would incorporate more blue and white china into the china cabinet to make more of a statement. Add another element between the two ginger jars if you leave them atop the china cabinet such as a plate in a plate stand or beautiful bowl. Alternatively put the two ginger jars on the dinng table when the table is not in use with a bowel of fruit between. If you have a buffet or side table in the room place a pair of large blue and white lamps at each end to add to the blue and white porcelain scheme. China cabnets don't need to always house china. You could store books, collecions or a mix of objects instead of china.
