Description

An entry for the 3D Editor Challenge Based on "[Littlest Tokyo](https://sketchfab.com/models/d5ca33dacf10459a92a8de25fb362a23)" by [glenatron](https://sketchfab.com/glenatron), licensed under CC Attribution-ShareAlike. I've dealt with the main lights and added the environmental impact on the whole building to make it look comfortable in every place around; you can clearly see the changes of the whole building before and after the cold and warm, including the direction of the light source has done a lot of tests, and finally please enjoy.
