Hi! All of my stuff is on the creator's page: https://pizzadoggy.itch.io/
I cannot check at the moment how many triangles/vertices they have in general, because I'm already in bed, but all of them are quite low poly. They might appear more detailed in the showcase images because of the smooth shading of surfaces.
I'll let you know the total count of the triangles/vertices in the morning, but keep in mind that the packs have hundreds of items in them!
