I do not see the wall in the picture. I think the shades of grey on the floor and tile planter tile looks great. You might consider a light version of those. It really depends on the amount of light you have in the room.

I think you need to have a well defined entry - looks like there are three or four ways to get into the home. I actually wonder if the other side of the house, not shown in your photos, would make a better front side and this one a better back side.Glad your daughter is recovering.

What are the dimensions? If you are afraid space will be too tight, you could skip the table and just do a grand lounge area: start with a 4 to 5 ft diameter round or square coffee table, then surround that with a U shaped sectional.

Since you have white and black windows, fans, doors, gates, you need a light tan beige rather than an off white cream - off white will just look dirty next to the white. Something that goes warm neutral instead of yellow will work well. Tropical can mean lots of different things to different people - pick one accent color - a lagoon type green-blue-green with large leafy palms, and add a sail shade (triangle shaped) in the same tone to the upper deck.
