Eterna-Giganta-Dynamax Castform (Joke)

Concept Art for a "Fake" alternate form of Castform, inspired by FalseSwipeGaming's "How BAD was Castform ACTUALLY?" video. At one point, the video jokingly proposed a powered-up version of the otherwise pitifully weak Castform where it uses all its other forms combined*, and that's exactly what I designed.

* Castform has sunny, rainy and hail forms, but also was proposed in the video to include sandstorm.
