Great colour choices! I agree to go with the grey rug, but you can use the yellow as a subtle highlight colour in the design. Here is a photo of our Clover rug in grey and cream , but you could easily make the cream a light yellow. At Tsar we custom make rugs to the exact right size and colour combination to ensure you get it 100% right. Have a look at tsar.com.au. We'd be happy to assist.

I can really recommend the Danish brand "Rug Solid, which have rugs made totally out of recycled materials. This is a photo from our living room, where we have a recycled cotton rug from "Rug Solid". http://rugsolid.dk/en/

The room looks lovely. The rug is too light in fabric weight - it could be dangerous if someone caught their toe under it. And as mentioned by others - you need some colour. I know that it is advised by some people that a mat should go under the furniture, however, that is not always possible.

Rug looks good. Don't get rid of your coffee table. Just slightly sand the top and pick an antique white or light grey paint with primer already in it and give it 2 coats. It will come up great. wouldn't take long to do. Add a tray with candles and small artificial plant, *& would look great. Good luck.
