Looks like you have several things to consider in the layout. What the view out the window ? Do you really want to see more of whats outside? Cooking is always best on the outside wall to get it vented, island cooking is a last resort, downdraft dont work well at all and the island hood is typically obstructive. Looks like the wall should come out to open the space up. Best advice is to have a designer come to your home and see it in person. There are costs associated with every change and it is very difficult to judge just from photos.The design phase is the most important part of any kitchen remodel the builder is only going to install it as the plans layout. Find a great designer that makes house calls :)

That's a fabulous idea. I don't like that front board but it's lacquered to coordinate with the cupboards, so ot couldn't be painted . I could keep the stools and improve the hated kickboard. That would be a double win. Although a lower back would be nice. I kind of like those white lattice designer ones, would they be too busy?

squeakerd - it is really hard to get a perspective on the whole area but if this is part of a much larger area then I feel you need to first decide just what you want as the end result. Do you just want your entire area to be one open plan or do you want to break it down into visually defined areas within the open plan. As you have the area now, I don't feel any cohesiveness between your table and the sideboard, I think I would move the sideboard to the end wall, it looks more like it would belong there, even just by the shape of the room. Definitely a larger rug will define the space better - just be careful of any trip hazard with the door nearby - but before you decide on the rug, consider window dressings and whether you want things plain or introduce some bold patterns and what colours look best in the area. Artwork can go where your sideboard is now, but again think colours and impact of design on the whole area. It is all very well to build a room around one piece, but you need to look at the impact that piece will have on other items and what limitations it could cause. I would suggest you set aside some serious time to look through photos on Houzz, especially if you can find areas similar to yours, till you find what appeals to you, put the photos into your ideas book and use that to build your room. I have found this invaluable in the past and it has saved me many an expensive mistake.

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.
