Maybe I would make more interesting graphics.
This does not seem to be a visualization, so we can not support you.
You use quite violent graphics, so maybe it would be appropriate to combine it with something a little pleasant, so that there is a clear contrast between the "bad" outside and the peace inside. In this picture, I would choose more pleasant colors and visuals, still a little playful. Because when all the visual elements are unpleasant, it will be difficult for the average observer to spend a long time. It should be visible visually that this is a place where it will be pleasant to be.
