Hi. Yes. The next packs (after 105) will be something different from previous ones.
Do you have any suggestions? I have only "sci-fi" in my mind=)
It would be good to set a specific theme. For example, school, hospital, spaceship, arcade, etc... Or it might be fine to reference a specific building or floor. (In the case of sidewalk blocks, tactile paving for the visually impaired, crosswalks, or asphalt road patterns, etc.)
Please understand that I don't have an extremely high level of understanding about PBR, so I apologize that I couldn't provide better opinions.
