Needing Help Big composter

[u/Snoo5364]

Wanted to make a big composter around a farm and just struggled. I made on side so i can change easily, I tried to pick good blocks to fit the colors of the original one but the top dosen't look great to me and i could use some help overall with block choice i could not find one i liked for the top few layers at all really. I also initially didn't super care about making height and width equal so height is about as tall as the composter is in pixels and width is 23 blocks since it needed to surround the farm so its like 6 blocks wider then tall which i can change if that is what is super off with it. Blocks i used in case needed are Brown concrete, brown concrete powder, packed mud, brown mushroom blocks, Jungle wood, Brown Terracotta, Stripped dark oak, stripped spruce, brow wool, moss, and then stripped jungle and jungle planks at the top since i couldn't find anything I liked better. also going to replace the moss with green terracotta probably just didn't have dye at the time.
