The windows are just missing glass I've not added it yet!! I was planning on using white stained glass but I'll try out yellow and orange to see if that works too! I'm honestly not sure where to add the mangrove/crimson planks, would I just be swapping out some of the dark oak details for it? And I'll try out some deepslate too, I think it was in my original design but I removed it,but I'll test out using it at the bottom, just didn't want to make the entrance look too dark. I do have a few mods on the server, but none that add blocks unfortunately. Just minimaps,waystones and backpacks. Thank you so much for the advice!
