Very nice house and yard!
You have a large imposing two story house and plenty of yard room. The chief mistake almost everyone makes is to go way too small with foundation plantings, making one row of small plants in a straight line across. All out of scale with the large house, unnatural looking, boring, adds nothing to the looks of the house.
All your foundation planting areas are too small and too rectangular. Your house is a big box. You want to soften that with curves. Extend your beds out every where you can and give them curved front edges.
Here's a couple of previous posts on front yard landscaping I did, with inspiration pictures. Look for more inspiration pictures. You can just do a search on "front yard landscaping images."

Just had to throw a picture in, because the post looks so boring without it.
You want your front door to stand out and be welcoming. I'd paint your front steps a contrasting color and put white banisters/stair railings on them to match the porch railings. Then make a curving path from the steps to midway down the driveway, where guests would park.
Put in all your hardscaping (paths etc) first and then trees and shrubbery. Worry about filling in with flowers later.
When you plan your plantings, think about having something interesting going on in four seasons. Here's a couple threads I did about four season gardens and winter interest:

So evergreens, things with colorful fall foliage, things with colorful foliage period, things with winter berries, etc.
Some shrub suggestions include: serviceberry, purple ninebark, viburnum, yew, vaccinium (high bush blueberry). All of these should be good in your morning sun location and cold hardy for you.
