I would use plant troughs both inside in front of window and outside against the block wall. If it will grow a small variety of clumping bamboo against the outside wall and Sansivieria or philodendrons dotted with colourful Bromeliads in front of the window. I would prefer dark furniture for tropical look, replace the bar top with a Bamboo ply perhaps, or even use lengths of decking timber to cover the back wall or create a timber feature. Add colour to soft furnishings with bright greens, oranges, yellows or aqua blue. Soften edges with white sheer curtains and add Potted Kentia palms in interesting stone planters. I think the floor would look better natural than painted so polishing it to reveal the indivdual stones sounds great. Don't forget a little LED uplighting. Totally depends on the budget.

These are often seen with colours in the beige to salamander range on walls, so how about a lemon yellow or peach for a different take? The awning is probably needed, but you might look at a fabric option to freshen, as well as an arbor over the garage, and toning down the colour of the driveway. Window trim will just barely show in any colour( they played up just the picture window in the photo below, and painted out the rest, which might also look well on your house if you matched your awning colour to your picture window trim) - and a clay brown shade on the trellised area and flower bed wall will help keep attention on the plant material. Paint out the garage. You could also use some additional lighting for the garage and the planting beds ( consider widening the curve of the latter).

This space is a little too tight for shrubs like Roses or Spirea. I would stick with ornamental grasses or other perennials that will thrive in your sun/shade condition. If you are in full sun I would recommend Coreopsis, Coneflower, Liatris, etc. This would also be a fun space for annuals and tropicals. Mix in a few larger tropicals like Hibiscus, a small Palm, or Croton with your typical annuals such a Geranium and Margiolds. This space could also be used as a vegetable garden. Mix in a few herbs or vegetable plants with the annuals for additional foliage color and texture. Good luck and have fun!

Georgia is at the most a zone 8b climate so there is a limit to how much of a tropical look you can manage. But there are some very cold hardy shrubs and plants you could try that will emulate a tropical look. You can try reviewing some of the posts from the Tropicalesque Gardens forum for some possibilities. Generally, anything with very large foliage will provide that effect - Fatsia japonica, aucuba, edible figs, hardy bananas, perennials like alocasia or acanthus, And there are also a number of cold hardy palms you can try. I might keep some of the hedged shrubs, especially those close to the entry. They provide an nice evergreen backdrop against to display the less tame looking tropicals. You can always reduce the height as necessary.
