the white paint is quite harsh agaiinst the dark brick.i'd tone all of it down with a putty,charcoal or deep brown. your home will look much more expensive.
browse houzz exteriors/brick with dark trim. you'll find dozens of examples.

chunkier columns would look better.

put together a long term landscape planusing native low maintenance plants including flowering trees and shrubs. you may want to hire a pro to draw up a plan you can do yourself in stages.
congratulations on your lovely new home.
