The illustrator of this double page splash is not identified in the magazine. It’s in the middle of the latest installment of Pocsik’s Starcrown – an episodic piece of text that’s been ongoing for the past few issues. The art has varied significantly throughout the serialization, but occasionally stuff like this pops up, prompting the reader to slow down and just stare at the action.
