I just had an incredible idea for an addition to this, though I'm not sure if its possible or how easy it would be to do. I was looking up at the night sky for about a second and had a thought. Why not add the constellations into the night sky? To me, that would be incredible.
Updated to work with 1.3, used recolors from a previous poster and recolored logs for birch trees, and recolored cobble for sandstone,the beds and repeaters are just high def versions of the original model.
edit: different download link, I messed up with the sandstone on the first one.
