"Aura farming" as a term may apply in scenarios where the character deliberately tries to look cool and impress others (hence the "farming" aspect of it), but it has zero relevance as a term for scenarios of characters who just simply HAPPEN to look cool without trying to be cool.
The character in OP's picture (presumably) isn't trying to pose for anyone.
He's simply made to look cool by the mangaka for what looks like a double page spread.
Within the context of the manga, he's simply a samurai general/commander riding his horse in front of what appears to be his army.
