Pressure wash the brick, paint the shutters and front door black, and add some garage door hardware.
A multi tiered flower box under the small front window would be great for adding some colorful seasonal flowers, and try to tie them to a lush green wreath on the front door.
The back patio looks great, just add an outdoor rug under the dining set, add matching cushions and umbrella. A few potted plants would charm up the space as well.garage door hardware
Cute house.
Here's what I would do:
Yes to getting rid of the bushes. Especially the ones tight to the house.
Unless you're willing to paint the brick or redo the shingles, those colors are where you start. Find a color palette you like that includes those colors (I like using this site but there are many websites) and repaint the siding and trim.
Take a drive around your neighborhood and try and identify landscape designs that a)trip your trigger and b) match the general layout of your property. For plants, I'd find an arboretum near you to pull names of plants you like. Check and see what local gardening clubs exist, they're full of plant nerds who can give good recommends.
Vertical wall garden!
There are lots of ways to do this and none cost very much. If you hand it onto the house, I would put a clear shower curtain liner behind it to keep the moisture off the wood. If it’s shady there, you can place faux plants.
