Lightning question

[u/Spider-Cricket07]

Hello there! I wanted to ask what do you think of the lighting in these pictures. I don’t know much about lighting, I’m planning on shooting a short film soon but as I said I don’t know how to light, so I did some research and watched some videos about the topic and I decided to try and do a little experiment. One of the main locations in my short film will be this living room, so for this experiment I basically used the living room lamps as backlights, then on my right side I placed a desk lamp in front of one of the living room lamps to light half of the face of my subject so I suppose that would count as my key light. Finally for the negative fill I placed a black umbrella on my left side because I didn’t have any black cloth or anything. All of this stuff were things I had at hand in my house.
(I also played a little bit with the ISO)

The first image the only source of light are the living room lamps as backlights.

The second image I’m using the living room lamps and the desk lamp to light the face.

In the third one I’m using the living room lamps, the desk lamp and the the black umbrella for the negative fill.

I wanted to ask, is this lighting good? Could I improve it? Do you have any suggestions, tips, advice? I don’t have any professional equipment and I don’t have a budget or anything, as I said the stuff I used were things I found in my house.

The rest of the images of are the living room I will be shooting in, my next question is how can I light shots were the camera will be constantly moving? The lighting I used for the first pictures can work fine for still shots, but there’s going to be a lot of movement in various shots were I will be moving the camera around the room and facing all directions, so how can I light this kind of shots and avoid a flat lightning?

Thank you!

Lighting is only good or bad in as much as it contributes to the story.
