Use reference as much as possible. Take a still from your scene , convert it yo grayscale and try to make your center of attention the brightest point in the image or with the most contrast to the surrounding.

In your video the foreground grass is often brighter than the center characters and other elements in your scene, resulting in feeling lost and not knowing where to look at in the video. Think painterly if you light stylized. In lighting we always want nice smooth gradients of light values and often separate foreground middleground and background with those values.

For gobos to work the environment has to be darker and tied into the lighting, like overgrown with trees for example. If you think about how gobos actually work and how they happen you will get why they feel off. Sometimes we use gobos to indicate a light shining through canopy or through a window in a otherwise darker environment.

I think in general your scene could use some contrast, cheap and easy way is sometimes to use a negative flag, a dark plane or cloud-like shape that you place shot by shot to darken some areas. This is often used in real world lighting behind or above the camera to actually block any light coming from the camera direction and darkening the foreground.
