he looked better at 21
and no i dont think he looks lilke arnold
hes white, and a bodybuilder, thats about it
both arnold and luke have goofy faces too, BUT arnolds face was handsomely goofy, luke looks retardedly goofy
he phhysqiue is nothing like arnolds
his overpowering legs are about the same size as arnolds legs, and arnolds legs were overpowered by the rest of his body.
and NO you are not natural luke.
