Hi Sarah, I would go with a large rug in the lounge- if you can get all four feet of the couch on it as well as the tv cabinet it will create a clear ‘lounge room’ zone. This will be a costly rug due to the size. You can choose a piece of carpet that you like and have it cut and edged to create a customised rug if your own. Adding a large pendant over the dining table will mark this as another separate zone. I am personally not a fan of pendant lights over the island, I just think they add clutter to the space and have been overused - I’m sure many will disagree. You can have another row of down lights over the island if you need task lighting there and add led lighting under your overheads at the back as an accent light that will create a soft wash of light down the splash back. Finally ( even though you didn’t ask!) the white powerpoint to the front of your island stands out agains the black and works against it, swapping this for a black outlet will help make it disappear.

I would remove the globe, then with hot soapy water wash the entire outside of glass pendant and if your hand can fit, the inside as well. Maybe even a quick spray of a cleaning product like Ajax spray and wipe to get the grease off the outside, before wiping over the entire glass pendant. Obviously you will need a ladder to stand on to reach pendant safely. Make sure the glass is room temperature, not hot.

I think the light suits the design , and agree that 2 would look better -- the problem you have now though is that , even if you connect the wiring together for both lights ( so the existing wiring is all that is needed ) , is that you will need 2 new holes in the ceiling ( that top fitting covers them ) BUT you will end up with a hole where the existing wire comes through . On a new build , if you fill it , or even cut out a larger square and get a whole new cut-to-size panel in there and plaster and paint , its possible you'll see the different paint colours , and possibly the filler shrinks or gets a little dimple . Its do-able , but its time consuming ( $$$ ) to get it correct now . In other words , it will be at least in the $100's , so how much do you want 2 lights ?

I would call it a glass bowl hanging light. This company sells them as new replications. I'm sure yours would be worth more because it is original. https://www.fatshackvintage.com.au/products/chateau-glass-hanging-bowl-light
