Yeah, sharper teeth look a lot better, kinda menacing and stuff.
Although the fact that makes me sad the most is that Sanji never got a longer fight vs Kizaru, just tanked a couple of attacks and blocked one kick, and on top of it, let VP die. I mean, if he wasn't trying to get VP out per Luffy's orders, he could've done a better job of protecting him as he'd be 100% focused on Kizaru and could've blocked those "wound cauterizing" attack as well...
