No on the window because, IMO, it is too shabby chic for you home…lovely, by the way.

Indoor/outdoor runner up to front door; rattan furniture, all working with a new front door color.

Suggesting B.M. Somerville Red for the door AND the storm door. Art, instead of the window, your choice, of course, this is from greatbigcanvas.com region Florida.

Out door sofa (love the look) and indoor/outdoor runner are from all modern.com.

The faux croc pillow cover is from etsy.com. Instead of 2 18 x 18’s, I think three lumbars would work out better.

Couple of garden stools in white. These are from Hayneedle.

Add perennial climbing vines on the columns. Would ever consider painting the columns black?

I agree with Judy that the windows are a bit too rustic for the style of your house. Seasons are so hard here in Florida, especially if you're originally from somewhere that has 4 seasons. It's hard to be able to get away from the feeling that things look the same all the time! You can definitely choose a warmer color for your front door. I would paint the storm door the same color so the door appears larger and the color really shows up. If you find an inexpensive area rug, you can change the colors of the rug to warmer colors for fall and winter and cooler, more traditional tropical colors for spring and summer. Find furniture that works for year round and change pillows for the seasons as well.
