I think cherry glass would cheapen it. Have you considered a mirror glass, don't know if I would like to maintain it but others here swear by it. Tiles like Earp Bros suggested look good. I also like the glass mosaics but they might be a bit blingy for your room. I went back to laminate for my new kitchen and I really don't think you can beat it - it just looks so clean and uncluttered, and better still, it doesn't break the bank. Congratulations on a beautiful job.

Are you keeping the blue carpet? I would suggest if the carpet is staying to use a band of the dark blue colour on the bottom of the curtain, say around 50 - 60 cm. Then the main body of the curtain to me made from a textured or even self patterned off white or natural oatmeal coloured fabric. (See attached pic) This will marry up the flooring with your walls and the lounge suite.

I'm going to suggest these grey Montage tiles. I think the Como tiles are nice too. Dark grey will add drama and balance out the dark sink. The mixed tones will tie in the variations of grey and silver in the bench tops, appliances and glass door frames. The stone/slate look will add a natural element to complement the wooden floor and balance out the laminate. If you do go for colour, I like Bernadette's suggestion of complementing the glass colour. A tile that looks like pale jade might be nice.

Please post photos of the space as you will get better help.
