Here is my latest set. It is my first station set under the name Ardy, my first wooden station set, and my first set this year, so it's a triple record breaker. I hope you enjoy it and please leave a comment telling me about what you think about it.

This set contains a series of wooden walls, some tipi's, cactus, dead tree branches, wanted posters, (animated) vultures and an animated mill for all your Western themed parks  :)
Keep in mind that this set is far from finished but I just release it as it is :)
Total amount of objects: 89 items (Walls, General Scenery and Foliage)

Thank you and Happy Holidays everyone! :)
