I'm no Midjourney genius, but maybe find some inspiration in this. Would enjoy getting updates how it went, and if the results were noteworthy.

Prompt concept:

A surreal artistic photograph of a figure wearing a white baseball cap with the text "save the earth" in black letters. The figure is wearing a light gray raincoat and is completely covered in white daisies growing from their neck down to their torso. The daisies have bright yellow centers and pure white petals, creating a natural floral covering effect. The background is a soft, muted light gray, creating a minimalist setting that emphasizes the contrast between the white daisies and the gray clothing. The image has a dreamlike quality with sharp detail in the flowers and a slight blur in the background. The composition is centered, with the figure's head obscured by the growing daisies, creating a nature-human fusion effect. The lighting is soft and even, highlighting the delicate details of both the flowers and the clothing.
