This is a cool photo!

My main critique is that there is too much light on the left. I think the composition would be stronger if the camera were closer to your daughter to show the light hitting her face, and possibly with more darkness behind her. The squiggly lights in the background are fighting for attention with your daughter, when it really feels like her silhouette (lit by the light in front of her) should be the subject.

I like the colors though, and I don’t think she’s too dark (like you mentioned). Great photo! :)

I agree with @clicky there there is too much distraction on the left side. With how the photo is now, I would suggest a vertical crop with your daughter and clam as the main subjects. Cut out what you can on either side. I personally really like the photo cropped in this way.

I think for another photo idea you could kneel directly behind her at her eye level or maybe lower, and capture her whole silhouette as she looks at the light sculpture. Also, with all the amazing colors I also think you could try framing her face at her eye level, up close, with the various colors of light hitting her face at an angle to capture her expression.
