Just do it like every other walkway from the driveway to the door. There are millions of them. I can't think what the question could be.

Yes, it's much needed, but also a porch.

For good landscaping it is important to keep the new walk at least five feet from the house. I would build it with ordinary concrete to match the other walk.

All the existing shrubbery could use replacing too.

Agree ... the plantings could use replacement.

Though you can get an idea from a perspective drawing, a walk is something you'd lay out in plan view in order to confirm that its route and details work correctly. IMO, the right end of the house seems vacant and exposed. A small to medium tree would have it looking protected and integrated into its surroundings. I'd plan for that and then route the walk around this tree. I would consider 6' to be the minimum distance a walk should be from the house. More is better as plants take up space and squeezing them tightly between a walk and a walk doesn't look good ... especially when there is an expansive lawn immediately on the other side of the walk. There's no need to cramp thing tightly.

A roofed porch would certainly add an inviting quality to the front door.

With dark trim and a planter:

If there is no street parking, will your driveway accommodate enough cars when you have company? Adding parking should be planned at this stage. It doesn’t have to be pavement but could be pavers set in grass. Don’t have the new walk force people to squeeze past cars.

Ooh, Yardvaark, I love your curved walkway. I hope you don't mind that I stole it.

".... Yardvaark, I love your curved walkway. I hope you don't mind that I stole it." Of course not! Whatever I post here is up for public consumption.

some ideas:

I have a different take on your walkway dilemma. Looks like you have lots of property to work with here. I would make a lot of the space directly in front of your house into usable space rather than just grass and yard. I'd add a huge patio area from your front door to the driveway, big enough to have a sitting area (instead of a porch) and perhaps with a curved edge. So, no walkway. Patio instead. Then I would add huge curved flower beds in front of the patio area on both sides of the front walkway. In the flower beds I would plant a couple of trees for height and to soften the harsh horizontal line of your house. You have oodles of potential here. Your house could be stunning. If the budget allows, consult a landscape designer. Good luck!!
