Thank you for the feedback. Can't say for sure when i will get back to this, currently i don't have much time on my hands to devote to this particular set. Whenever i'm on PlanCo nowadays i usually work on my rides and parks just for leisure or have a break from RL, and share some of the items i make for ride-specific projects. I will eventually get back to them, but can't give an estimate at this time as to when that will happen. Stay safe & healthy! :)
(Update: currently i'm planning to get back to work on the signs in May)

are there more letters? ideally the entire alphabet.
thanks
