Looks like plain jane white doors and window trim and the house looks (in the picture) sort of off-white/yellow/cream.
Is there exposed rafters I see painted brown with a shingle roof?
For some ummph perhaps some dramatic trim and door colors for that ummph, more bang for the buck and more ummph.
Power washing the driveway, especialy those stains under and behind the yellow car, possibly even staining (using the multi-toned staining method so it looks more like natural stone) the concrete driveway with another interesting umph shade for drama (consider the walk path materials mentioned later regarding coordinating the look).
Possibly reconsidering that plant/tree which does nothing to harmonize or flatter the detail of the house (in fact hides the bay window isn't balanced in its placement and just brings attention to the driveway and garage doors)...and doing some serious organized and well planned landscaping, possibly some berm/raised planting areas and bringing a serpentine walk path to the front entry with a companion snaking path to the drive. More bang for the buck, more umph, more curb appeal and well planned and chosen now, will continue to increase in value as it matures.
A few dollars now spent for a professional landscape designer to draw up a master plan could be a fantastic return on your investment for something dramatic and distinctive. You could ask your designer/planner to propose a layered stage plan so you could work in stages as your energy, time, and budget allows, beginning with your main specimin tree work and walkway/entrance enhancement first. Could be done all this year, or in stages over the next few years. Introducing colors, depth, and textures with a design plan to enhance the attributes and detract/minimize the negatives, and adding interest and enjoyment.
