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.

The all black kitchen looks scary as. Maybe because there's no lightness in there at all.

Hello Rispah. Depending on how much seating you need, I'm assuming 2 x 3 seater sofas would be enough. I would consider the below layout. This option keeps the traffic from in and out of the exterior doors completely clear and creates a nice intimate setting for the living but still being open to the kitchen for social interaction. Alternatively you could have the sofas facing each other with one sofa backing to the kitchen which would be a more formal approach and encourage the view from outside those doors. If this option suited your lifestyle better, a slim styled sideboard is a great way to style the back view of your sofa.
