We have learned mix live action (green screen ) with drawing animation since two weeks. We learned AE and shooting skills, which helps with composition. But the mixed media looks is the most inspired point for me during the study.
In a short word, this piece of work put 2D drawing and 3D element together, build a unexcited time and space. This is a not very unusual technology, but if we discuss this kind of skill, as a new language in animation, which could bring a lots possibilities. (what I mean by new animated language is that the narrative is not according timing, or space any more)
