Was it from this Amazon seller? Reviews seem to show it's alright but how good the print quality truly is really depends on the quality/post-processing of the stolen artwork from (yes stolen, it's fan art allegedly* from this artist that's been sold everywhere for a decade) and how well their canvas/print materials are.
Mostly Chinese printers make these multiple set pieces so you're kind of stuck with a long wait regardless. Some online US and UK print shops will print whatever you want regardless of who "owns" the image (it's how I got my manga Vegeta posters) so to ensure top quality you could take the image and find such shops but it will cost way more for a 5 piece spread especially canvas, ~$200+ at the lowest depending on size.
*I say allegedly as I've seen so many versions of it I really don't know who made what originally.
