Here is some concept art for 'Circle Of Sphere' I made when I finished the model for the ball character. I modelled/drew the 3 different areas I wanted to have in the animation and then composited the character on top. You may noticed that the third area was originally meant to have a green sky, but at one point I had exported the animation as an MP4 which meant that any transparent backgrounds became just black, and a lot of people I showed this to preferred the black abyss over the green. I prefer it as well now, it sort of makes it look like the middle of night along a highway that these vehicles are driving through. The end of a work day, and everyone is going home. I don't really show this type of world building but it is meant to be sort of a head canon for everyone else to imagine and interpret.
Here is also a full view of the entire map, since the camera never cut to anything, the whole thing is in one scene. Keep in mind that I animated things that would be seen on camera, because there is not point to animating something that is literally off camera. So this sort of breaks the illusion of the bigger world but I hope you can forgive me for that and know there is more out there then it meets the eye :)
More stuff coming in the future! Stay tuned! If you have any suggestions for other stuff to show off or explain how I did do ask!
