Never thought of shutters... And the trees are going to be replaced.

Is there a path to the front porch? If there is, landscape around it to make it stand out. If there isn’t, congratulations, you have a blank canvas to do anything you want/can afford. Plus everything BobbieH said, too.

Actually, you might consider taking that tree down altogether. In the photo it looks very close to the house. This could mean foundation damage from the roots, and in a bad wind, it is close enough to do a world of damage/injury.

I can barely see the house because of that tree - it needs to go! Once it's gone you'll have a blank slate. Lots of options for what looks to be an adorable house.

Any ideas how/with what to frame this house? Thinking about some smaller (and hopefully flowering) trees across the front. Is that a bad idea?

As pointed out, the central tree is a detriment on account of being so close, and being disfigured with too low of branching for the situation. If it's going away anytime soon, it would be good to get pictures without it.

Another detriment is a walk that is too close to the front of the house to allow for a proper depth foundation planting bed. Any possibility of it being redone?

A third detriment is the big green woolly "bear" positioned next to the steps, waiting to ambush anyone coming or going.

No doubt, you'll want to add new plantings after resolving those things. The pictures you've provided, though, are not great for giving you graphic feedback. I suggest you retake them with the camera positioned in line with the center of the house, and at a closer distance than the first picture. You'd probably need to take them from the bed of a pickup or a stepladder that is positioned at the toe of the slope. Pan from left to right taking slightly overlapping pictures so the whole scene can be captured contiguously. Include space beyond each end of the house. Don't reposition the camera between pictures except to pivot.

Changing the house paint color could be an improvement. White strikes me as plain and uninspiring. I find medium tone greys* with white trim to be overall more desirable.

*Could be a variation of greys or taupes or lean toward a color ... but not BE a color. Avoid beiges & brown, especially in that combination .... so overdone to death and 30 years stale.

Tree siting and choice is a big deal. Perhaps the Tree forum could help you choose more wisely than the previous owner.
