if the blinds are not new or ready for replacement you could replace them with natural wood plantation shutter and then just have a sheer fabric in front of them. I would also position a chair in the corner of the window to break up the blankness of the window and then you could soften the room further with pot plants.

The market is full of tropical/botanical art at the moment which lend themselves well to tropical or beachy looks. The look you are after calls for natural textures with a soft colour palette, think linen bedding and layer it up with throws and cushions for texture and pops of colour.

In my opinion drapes are not a good option in your room as the ceiling slopes to just above your window at a certain point. This would dictate the height at which your drapes hang and, in this instance would be too low. To soften the windows, I would have a tall palm or Fiddle Leaf Fig tree in wicker basket. It also looks like you have the space for a chair.

Thanks very much, any idea where I might pick up some suitable art in Auckland area?

Have a look for art on Trade Me you never know what youight find & then you are able to cover off the entire country from the comfort of home. Art is a very personal thing so you really need to find something that you love.
