A picture from further back would help. What about the area where those two ground level windows are? Do you want to make the porch deeper? At first glance I think a much larger light fixture is needed ( I realize that wasn’t your Q. )

something like this, maybe with railings or without, put out some planters etc?

Given where the basement windows and the bumped out window are placed, I'm not sure this will work as you imagine. This may be a bigger project than you think and would be worth having an architect take a look at it.

Sabrina makes a good point.

FWIW, there may be other ways to improve the curb appeal. To me, the railing feels off-putting since it's across the doorway. One option may be to remove that and add a nice curved walkway (from the street? or closer to the end of the driveway?) that approaches the center of the existing porch. You could turn that grassy area in front of the basement windows into another planting bed. With low flowers there, the light would still get in and the flowers could even be seen from inside as well as out. I like the idea of a different color door. The shade of blue feels too bright IMO. BTW, if you are willing to post a pic of the whole front yard, we might have other ideas. You might gain a lot of curb appeal by changing the landscaping. The little flowers in front of the bay window are nice but that spot might look good with a bigger planting bed and taller plants in the back next to the house.
