Wow, big difference, love it!

Really don't know about your china cabinet, would be tempted to remove the top; do you have other available room for your china? Also don't know if that would look like just too much "flat" in your dining room, but maybe a nice picture and a few somewhat tall objects on top.

That looks great! Glad it worked out. You don't show your whole hutch, but I think it looks fine, as is. The color coordinates with the floors and the rush seats, the other black table brings some balance. Not sure how it would look, but I might just try some black cabinet pulls on it. Or maybe paint/paper the back of the shelves black....If not, I think I'd leave it as is.

Here's a better pic of the hutch. I will definitely need new knobs at the very least. I also like the idea of papering or painting the back of the shelves...

I love the mixture of wood stains. I would leave the hutch in the room and decorate it with black objects similar to this combination:

I like it as is, also, but I think adding black pulls is a great idea.

If you feel that you *must* paint it, how about a medium blue or blue/black combo that plays off your walls?

I like the hutch and how it picks up the chair seats. Black is my accent color but I use it sparingly. I would pull back on the black a little--for instance, the hanging over the doorway and the tabletop items. But I feel the window area needs a touch of black, maybe in new black and tan drapes or by getting a beefier black curtain rod.

The new set really makes the paint come alive and your black accents POP! No way could I give up any part of your china cabinet. You added a "side board" ( great idea) so you can keep the height of the China cabinet. The ideas here are worth a shot, one at a time until you find the right "fix".

I love it! I was hoping you would get it. The room looked washed out with the other set. The new set changes the whole room. I personally like the hutch as is. I think it makes the dining set pop more. Changing the knobs to a dark color would look great.

I love that Hutch! I would leave it as is the colors look great together. Adding new pulls and knobs can update things, I think the cup style pulls would look good on it.
Great job on the purchase!

Looks great. I think the entire hutch in black would be too much black. Perhaps painting just the countertop portion of the hutch black and adding black hardware would be tie it in a little more with the tables and chairs.

Olychick said the exact thing I was thinking.
maybe add a larged light wood framed art over the sofa table for balance.
