Last year he did something similar with the main mecha of Mobile Suit Gundam Iron-Blooded Orphans, only with a cel-painted aesthetic.
He went to the trouble of putting together one jaw-dropping three-dimensional model kit which he then colored, using colored pencils, to look like a 2-D sketch.
Hard as it may be to believe, the lovingly colored model started off entirely white, save for the lines separating the robot’s panels.
With decades’ worth of source material in the Gundam franchise, hopefully we’ll be seeing more of his interdimensional talents in the future.
