The "Portrait of Emilio Terry (Unfinished)" trail

a) Stephane Levallois drew this version of the Neomorph backburster showing it having erupted from the back of someone leaning on the table.

When I first saw it around December 21, 2017,perhaps I thought it looked like some sort of abstract Bakugan but then I realised that it appeared to reference Dali's portrait of Emilio Terry.

Ridley's response about the resulting drawing, "Good, but the creature, "plou petite...""
