Congratulations on your lovely new home! I think that some rather simple changes are the only things needed for now.

Remove the shutters and beef up the trim on the small upper window.

Remove that larger bush directly in front of the porch post. Then re-evaluate all of the landscaping.

Paint the porch railings white.

Remove the inserts in the garage door windows.

Possibly change the siding to sage green and then paint the garage door to match.

Replace the lights with something larger and spiffy.

Paint your garage doors the same color as your house. They should not be a "feature".

Too many colors going on. Gray, white, red, tan. The brick looks to have more browns in it. With that and your roof a taupe/clay color on the siding would look good. I also agree with losing the shutters, and working on the landscaping.
