My first impression is that it looks too fragile with not enough visual weight. It looks like something that would hang in a hallway near bedrooms.

Maybe try something like this? (Though this particular one might be too tall.)

It is a beautiful light but it doesn't read well for a few reason. It is glass against glass so it is hard to see. The black lines are thin and delicate so it is hard to see. The scale seems slightly too small.

I do think the shape of the fixture is nice and the vibe is classic but not overly coy. Can you find a similar light with thicker black lines and ever so slightly larger?

What is the height from the bottom of the fixtures to the floor of your porch? And from the bottom of the fixture to the step into your door way.
