Yes, i think it will be right decision to make a separate "army" for each year.
i will draw little chibi muzzle of each new character in my futured comissions.
This picture will grow ewery time i will draw new comission with new customer.
Dont worry, the basic option of this art with ALL my customrs started with 2020 halloween will be updated at the same time.
