That looks like a dream come true for anime artists outside of Japan, it looks like it would be godly for especially art done in a anime style, because anime relies heavily on coloring/shading for details, which would make it easy to make a 2D img look like it has 3D movement, even though the chat is drawn completely in 2D. It would definitely help someone make a great presentation, if nothing else(this way people/a publisher can see exactly what you want to do in a anime, without needing a million foot notes describing every action)
If It's as easy to work with, as the video makes it out to be, and "if you and sting multiple scenes together"(which the video doesn't mention, so if you can answer this, that would be great), 1500 sound like a steal.
