Based on the builds we see in this app and your last one, your work unfortunatley does not reach the standard we require for the rank up. Your work however is actually quite good, especially your mossy-cobblestone castle. It's detail is exquisite and quite unique. Build two more builds of that caliber and then we will accept you, unfortunatley rejected.
Dont get down though, your other builds were quite nice and had great shape, they just didnt have enough detail. Anyway, better luck next time.
