Never been a fan of matching lighting exactly, but instead suggest coordinating the pendants with your current fixture. You don't have to stick to ball-shaped either and can maybe go with a tubular shape. If you're hubby is stuck on chrome, maybe a chrome tube would work... if you want more glass, we also carry a line of pendant lighting and I'm sure you'll find something to go with it or atleast give you an idea.

If you want to stay with the Tiffany look you could try to find some small simple ones like these. Otherwise I like the idea of simple glass pendants with an Edison decorative globe.

If you go for down lights you will need to leave a gap around them of 100 mm between the recessed part and insulation so the insulation doesn't catch on fire. This also creates a problem with the thermal performance of your home because heat can move freely through the ceiling where there is no insulation. It can make a big difference even if there are only a few down lights. Also, down lights are very directional (send most of their light straight down) so you need to put more in to get the same effect. You could try track lights that attach to the ceiling instead. If you want a pendant go for something cheap and easy to replace if it is damaged by toys/clothes or whatever being thrown around. Ikea have lots. FYI dimmers don;t educe the power consumption, merely reduce the intensity of the light.

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.
