Haha, that's cool! Well, I used to chat with David Gould a lot, on the HighEnd3D forums, and also over email. Yeah, I really liked his Illustrate3D, but I found 3DSMax too frustrating to work with! It's such a complex software, with a really complex interface.
Just like in classical
Anime, I like the idea of doing the backdrops separately in a softer watercolor aesthetic, while doing the foreground animating objects in a vector-ish solid-colored format, which looks more cartoony. I've been thinking about trying Swift3D for this purpose. I've heard Swift3D version 5 is supposed to be a lot better.
Anyway, I really liked the soft look of your planet in the background.
But the Invid motherships look too 3D-ish, which really makes them stand out.
Anyway, wonderful movie clips. Can't wait to see how it all turns out.
