Astronomical evidence
Kepler-1647 b is a giant planet on a circumbinary orbit around two stars. Transit observations and orbital modeling established a long period of roughly three Earth years and a radius comparable to Jupiter's. [1,2] Its irradiation environment does not establish rain, lightning or a habitable satellite. The image places the observer on a fictional moon so that a solid foreground can coexist with a large parent planet. The storm is entirely part of the imagined setting.
The illustrated viewpoint
Small seated alien warrior with a rain-darkened cloak and low crest, seen from behind in meditation. An open rain-soaked field on an invented moon of Kepler-1647 b. The moon, breathable-looking sky, field, rain, lightning and warrior are invented. Kepler-1647 b is the giant above the land, not the surface being occupied. Clouds obscure the two real stellar hosts. Weather, planetary phase and local illumination are not predictions for this system; no moon stability or climate model is claimed.

All beings and cultures are fictional. Apparent sizes, phases and exposure are artistic, not a calibrated sky simulation. Cosmic connection is a visual theme, not an observed biological mechanism.
