A few personal opinions from my little experience:
- The strong blue light is up to you, depending on the type of film you’re shooting (so I guess such a blue might fit well in a sci-fi scene for instance), also if the scene requires the actor to open the door, would that blue light all come out, in that case overpowering the practical you placed above the door?
- What’s inside the door?
1. If that’s a sort of back entrance of a pub you can set up something like an LED emergency light? On the other hand if that's the main entrance of a pub you could place a red sign or something: this way you could really play with colors and contrast.
2. You could just hung a bare bulb with a shabby rain protection, that would fit that kind of place (just experiment with different sizes, types and colors)?
- Don’t use any practical and you can give the main actor a torch to play with it.
- I personally feel that this big street light off screen left (the existing lighting in the street) is somehow killing a little bit of contrast in the foreground, as if the wall is flatter than what you want it to be. And if you really want that practical above the door be the key light maybe you can diminish the intensity of that big source: if you can’t move it, you can wrap it with some NDs or kill it completely with a huge flag and replace it with a smaller fixture that would fill up a bit in case it'd be too dark. I guess the darker the alley the more powerful would be that practical you put above the door.
Can’t really say much with just a picture and knowing nothing about the story and the type of film you’re shooting, but I hope this can help you out and inspiring you at shaping your ideas and solutions on the matter
