I liked most of the suggestions , especially me me's , and was going to add a couple of my observations , then I got to the 'after' photo , and looked again ! Just my opinion , but there's no way I would have changed the brick colour -- not only does it look so fake , but your's is 1 unit out of 3 , which makes it look doubly fake IMO . And if it was charcoal , or off-white , it would still look jarring , but a dark blue ? Oh well . . . . . . . The red door is a great idea ( on its own ! ) -- as me me said , I would have left the trim charcoal , done the railing in the same , and the fence uprights ( posts ) the same . The initial photo looked like the fence palings were unpainted -- the latter they look painted , which is good -- with dark uprights , I'd say it would have all tied in . With brown uprights , blue bricks , natural railing , red door , white trim and a green bike ( yes , I know it can be moved ! ) it looks more like a kindergarten than a house IMO .

It's the landscaping I'd look at. The right (arched) side of your house is much prettier than the garage side, but is largely obscured by letter boxes and planting. The front path is an after-thoughty offshoot of the driveway. So from the street your focus is pulled to the wrong side. I'd demolish the mail box, and create a new pathway from the street to the front door, with pretty planting either side. Move the small tree in front of the door elsewhere, and keep the plantings in that bed low. Then paint the front door a bright colour, (yellow? turquoise?) to draw attention to it. Does the driveway need to be so wide, or could you curve in one side or another to expand your garden beds? Your lawn/existing beds are in fantastic condition btw. I don't love the driveway brick colour against your house bricks either. Don't really know the solution though.

I think the house is hiding in the garden , and the garden is 'old fashioned' . Basically , there's nothing too much wrong with your house , just the garden IMO . Less would be more . Make sure at least half of any view is lawn , and then make sure 90% of plants weren't on the best-selling list in 1960 haha -- have flaxes and grasses and cactuses , yellow leaves and red leaves , and only 1 or 2 shrubs that have mauve or pink flowers . Have stone gardens or bark gardens .

I agree about changing the style of the garage door but leaving it white. Agree about the tree/large shrub on the left. I wonder if the tree on the right is a poinciana rather than a jacaranda? Poincianas and jacarandas are beautiful but big, so you would need to go for a different tree on the left where there is less space. What I think would make a big difference is changing the planter 'boxes' on either side of the garage door and the low retaining wall. At the moment they look like stained cement or old besser block. If you can't afford to replace them, then just painting them will make a big difference. And refresh the plants. In particular, take out the succulent and plant something taller and lusher.
