Leather sofas can really dominate the room and can give an overall cold feeling. I would add some earthy elements, like a wood coffee table with glass or metal. Go to Restoration Hardware's website and look at their sofa room scenes. And I'm sorry I think the art is too harsh for the room. That's all your eye goes to in the room. too overpowering. I would look for something softer or maybe a cool mirror and I would add color to the room with pillows and some colorful lamps. I also think woven blinds would look great. They add warmth and give a finished look. The color of your window treatments should contrast your wall color a bit, not match it or else it starts to look generic and blah.. You have warm walls, warm floors and the woven blinds, like Hunter Douglas brand would pull it all together for you.

I love the seagrass wallpaper in first pic, so classy, you can pick up colour in the bedding and accessories, love the teal and orange

I would say definitely teak for outdoors in the tropical climate. Wicker would be fine if it's in a covered area. Here is an article about different woods for tropical climates. "The price of sustainably grown tropical outdoor furniture is becoming more and more affordable as the industry utilizes other varieties of sustainably grown tropical hardwoods, such as the following: Eucalyptus is a sustainably harvested plantation grown hardwood that possesses a smooth finish, lovely grain and a rich honey-red color that weathers beautifully due to the high oil content of its wood, and it smells good to boot. If allowed to weather naturally, the wood will take on a pleasing soft gray patina. It can be stained to retain the rich golden red color of the wood, however most people prefer the soft gray patina. Eucalyptus is less expensive and much easier to maintain than some of the other woods used for outdoor furniture. Balau is also one of the hardest of all tropical hardwoods. It is much more dense than teak and is in abundant supply. Like eucalyptus, it is more affordable than teak and will also withstand years and years of exposure to the elements. You will want to treat the wood occasionally with good wood oil if you wish to preserve the natural color, however this is a very low maintenance outdoor wood. Teak for good reason has become one of the most sought after of all the tropical hardwoods. Although it was at one time the preferred hardwood, along with mahogany, for ship building and decking, it is now grown on teak plantations due to its scarcity. The demand for teak is still high among those who are able to make the investment in furniture made from this beautiful top quality wood. Teak outdoor furniture is one of the more expensive options for outdoor furniture." http://www.thehouseandhomemagazine.com/Articles/Vol1No8/OutdoorFurniture/tabid/228/Default.aspx
