Robinette Front Yard- Curb Appeal
This is probably the closest picture we've seen to what looks like what you've suggested and what we like. If the gravel sections you're proposing are any deeper than in this picture, we'd like to consider setting large rectangular stones down into the gravel (so they're flush with the gravel) and use the gravel just as a border for the rectangular stone (see pictures I saved with this idea).
We don't like a retaining wall style like this without mortar
