Not really.
Oda HIMSELF said, in MULTIPLE OCASIONS that Zoro is represented by a shark, not a tiger.
Oda made that drawing because of some toy promotion that, for some reason, made Zoro a tiger.
BUt on SBS 95, when once again asked which animal Zoro was, Oda, ONCE AGAIN, says shark. not a single mention to tiger.
Shark Zoro is canon.
Tiger Zoro is filler.
:P
