Today we're analysing the technique used in a MOC called 'Avalonian Traffic Jam' by Henjin_Quilones on Flickr: https://www.flickr.com/photos/141735493@N05/28832745427/in/dateposted/
This MOC includes lots of great techniques that really give character to the scene, with highlights being the trees and fences that use parts with a thin profile. The roof has a very smooth exterior, created with various slopes that are angled using ball joints. The whole colour scheme of this MOC is subtle but the bright blue water and spots of flowers contrast well to this, making it a great little build.
