It looks like a 3d rendered graphic (like in the actual movie), not a 2d image. But isn't the software you are talking about just a 2d software? Also, how do you use it? Being Japanese software, it probably is all in Japanese language. Do you have an English patch for it?
I'm not sure. Maybe it's a hack. I got it like 3 years ago from a friend. About the "3D look", it's just matter of understanding how light and shading works and how do they look in animation and stuff.
