Research - 2D Limitations

The limitations of using 2D assets are that scenes tend to look very flat and it would not be possible to have an object spinning without creating an other assets that would resemble that object's in between frames. If you were to combine 2D assets with a program such as Maya however you would only have to create key frames for the object and the program would create the in-between frames for you once a 3-D model was made using the 2-D asset as reference. This would give an animator smoother movement in the animation whilst still retaining the look of a 2D animation.
Before i started my own animation I knew the limitations of the medium that I had chosen and did not want the characters to move much and have a more theatrical look to the overall scene, therefore i was not pushing the limitations of my medium but rather staying within them.
