Whoever made this tribute, you have my salute: The 3D CG, while quite obvious, blends very well with the rotoscoped animation, something that doesn't always happen (just look at some of Cowboy Bebop). It also captures the feel of Ghibli's animation amazingly well.
I salute the animator, and I also, of course, salute Hayao Miyazaki: Farewell, and may your legacy live on.
