In my humble opinion, the variety of nativity scenes makes them a whole world of their own in terms of art motifs. With all the possibilities open, I still decided to go for a very classic approach with mine, both in terms of imagery and building style. It has actually been on my to-build list for ten years, which is from before I even knew about the online LEGO community. Primarily this was a build for myself and my family to put under our Christmas tree, but there is also no harm in sharing it.
The construction is pretty basic with a generic stone wall and some layers of ground on the base, but there are still a few fun techniques that I have tried. The first one being 1×2 tiles connected to upside-down plates with minifig hands, which makes for some neat offsets and the texture you see. The downside of this technique is basically the same as with all of my other ones, that being its terrible fragility. There are ways of improving on it, but that is something for the future. The second technique is a bush/tree using a six stem flower stem piece as the basis and plates around it. I was inspired by a builder whose name I can not recall for the foliage, but when I find him again I will update the photo description on my Flickr.
