It might be worth while to consider the rest of the space also. Your breakfast bar/kitchen is located quiet closely to your dining table so depending on your kitchen space (apologies, I can't see too much of your kitchen from the photo) you might want to think about the overall style you want to achieve for you entire open plan space, and select pendants that would work for both your kitchen and dining. This is a project I worked on recently that shows how two different types of pendants can work harmoniously in the one space that is most similar to your kitchen and dining set up. Keep us posted on what you decide!

A couple of arm chairs standing either side of the TV, with floor lamps next to each chair within the window space for reading.

Hi Jayrees, I totally agree with what Kat had to offer, I would suggest a non geometric pattern on the rug as the floor is already geometric, a light colour and subtle pattern if you prefer a pattern. The mirror should definitely be moved and I would consider a large light print to compliment the new rug and and drapes. It's a pity that the window screen blocks the view (it's a nice view) but the heavy screen is a necessity these days, I would remove the stickers from the glass to help with the openness. Just noticed that you have an air con in the room so you may be able to remove the screen.

After 20 years lighting sales and domestic consultation the only advice is to make them equal distance from each other and from the edges of the island. You dont mention anything in or on the island like a sink so if its just work space make sure they arent to low that they create distinct spots of light, the idea is to provide balanced light along the whole benchtop. Also the fact they are such a solid construction they will provide a definite "zoning" effect, you could possibly raise the middle 1 to give a variation to the theme but after all its your home do what YOU want
