Cute house! I agree the shutters need to go since the double windows are much too large for them. I like the white but might consider pulling a color from the brick for the siding and garage doors. Since the garage doors are up front, they need to be less of a focal point. The white isn't doing that. At some point you might consider getting garage doors with panes across the top that tie in with the other windows. Paint the white downspout to blend with the brick.

In addition: beef up or make a big style statement with improved posts at the entry.

Improve the landscaping by removing all the little bushes and replacing with WOW factor plantings.

The siding is vinyl and cannot be painted, correct?

Shutters: gone. Garage doors:
