If you're looking for a change in style, our Nordlux Float pendants are really popular at the moment. There's a choice of brushed steel and brushed copper. The combination of the metal and the oiled walnut is really appealing: http://www.lightsy.co.uk/catalogsearch/result/index/?cat=11&q=float
I recommend this gorgeous pendant from Heals made of cork. It will add texture and ambiance to the kitchen scheme. It comes in different sizes and is innovative and not expensive.
Hi my only advice would be " your using your lights as a colour theme maybe similar types of lights in a neutral colour and change something else with a different colour theme if you want a subtle change
I would definitely suggest that you go with something metal or glass again but without using colour unless it is neutral cream, beige or black. Lights are generally quite expensive - so any accent pops of colour, I would add, would be in accessories such as tea towels, hand towels, spatulas, bowls etc.... I love the colours in the glass bowl that you have on the island - cannot really see but it may be figs???? Either way those pinky tones make your floor and kitchen seem lovely and warm. Good luck.
