Well, I dislike raining on any parades here, and everyone of course knows my opinion of the twin, who's just so gawdawful retarded one wonders how he remembers to breathe.
But this is no case of "like father, like son."
The son's talent comes nowhere even close to that of the father's; Atman's much much better, especially at caricaturizing people he doesn't like. (The son may not be into caricaturization, though.)
I think the twin's the superior "artist" of the two, and by a large margin.
<<<just stating an opinion.
