Lovely print. I had a peacock feather print and I had a colour called glacier Grey behind. Think it was Wattyl . Again like your other walls it is a greenish grey but darker. I also had my prints on a charcoal wall..loved that too. As you said the picture ties in with the chairs and now it's not necessary to add more matching colours. I'd buy a couple of sample pots and paint large pieces of cardboard. With the other walls I would consider painting them in whisper white (Dulux) a very universal colour that ties in nicely with all colours.

Personally, I don't think the all glass table in the second photo would work, it looks way too modern to compliment your existing furniture... I would still go for a glass top table, but instead of trying to find timber legs that will match the colour of your existing timber which can prove difficult, why not go for black metal legs which will pick up the black from your rug and that nice little black side table near the window...

It would be such a shame to rip up your beautiful floors, to try and do polished concrete now would be such a hard and costly job, along with the mess and the uncertainty of getting a good job that you may not like on completion as suggested, why not embrace your floors, decorate with the industrial look that you love , maybe a brick or concrete look wall could look really stylish and cost a lot less in $’s and stress

I took into consideration your new Fridge pantry alcove when I designed your kitchen to get you the max island and still being well placed within the kitchen. If the island isn't attached to the fridge wall you would need to leave a 1m space between them which would reduce the 3m Island as I have shown, the dotted wall shows the length of your kitchen, and how the island fits into that space, you could extend the island further into the dining if you wanted, I can redraw that for you. As I said with both of your plans drawn differently Both OKL and myself had a differnt result
