Let me first say that I love them all. I particularly like number three for my house :oP But, I think I like number two with the one you have purchased because it's a bit less formal than number three. I DO NOT like it with the beaded shades though. I think for a nice blend together you should do a fabric shade instead, and they'll look lovely together.

I'm not usually fond of drum shades, but I think that is gorgeous! Here are some guidelines I found for size selection "If the room is smaller than 10' by 10', a 17" to 20" diameter chandelier would be the right size. If the room is about 12' x 12', a 26" or 27" chandelier would look right. If the room is about 14' x 14', choose a 24" to 36" chandelier. A chandelier should hang about 30" from the surface of the table to insure no bumped heads and good illumination. A chandelier should be about 12" narrower than the width of the table over which it hangs. Total wattage of all bulbs should be 200 watts to 400 watts to provide sufficient light"

In my experience, most splashing comes off your hands and dishes, not off the bottom of your sink (never happens to me), so having the faucet reach into the center of the sink may be the most important factor.

I have a few thoughts I'm wondering if you and your team have discussed... Did you consider adding a wall between the present formal living room and the present dining room? It seems particularly odd to me to have this whole first floor totally open with two seating areas open to each other. If you added that wall perhaps you could turn the front room into a music and sitting room. The locations of the windows and doors across the back wall don't seem to related to the different spaces. I was thinking you could put a swing door between the dining room and the living room and another between the kitchen and the dining with windows centered on each of the three spaces aross the back; living room, dining room, kitchen windows. Did you discuss putting your clean up sink on the exterior wall and a prep sink in the island? I thought maybe instead of reach in pantries you could frame in a walk in pantry behind the fridge. The areas in teal are a reach in pantry on the left and a walk in on the right. Just food for thought...
