2D Versus 3D

Personally, I prefer working in a 2D environment as I feel that I have greater control over the style and design of the animation.
The drawing style and design in a 3D animation is restricted as the animator has to consider what would be a plausible model that they can animate. For example, an anime-style character would pose more of a problem in a 3D environment than in a 2D one.
I think that 2D animation is a very versatile medium as the drawing style and design can be easily implemented into 2D software such as Toon Boom Studio.
The problems with 3D animation is that the three dimensionality of the medium can result in a camera that is incorrectly positioned in the scene and it may be forgotten entirely. This is not a problem in 2D animation, as the camera is always directly facing the scene and can be moved, zoomed in or out or panned across the scene as required without resulting in odd camera angles.
I also think that 3D animation feels too remote when the animation is being created. The animator is kind of distanced from the building blocks of the animation; they are unable to physically change details of the model as it is being animated, the model, itself must be altered, then re-imported into the 3D environment.
Overall, I prefer 2D animation a lot more than 3D animation as I believe that it offers much more freedom to the animator than a 3D environment.
