From the looks of it, none of Shanks' abilities here are getting him off the hook of being a swordsman. A burning sword, and a way to counter FS/CoO. Also, confirmation that Shanks had ACoC before he lost his arm, which implies: 1) Shanks was a very high level fighter even back then, and 2) Mihawk likely has it too.
Of course, there's always the possibility that Shanks has several other powers/abilities that weren't revealed in this film. But I'm not seeing any haki Susanoo, haki kamehameha's, haki-formed arms, or martial arts like I was told. At the very least, this film isn't giving those people much to work with.
