Yeah I know this is not the best animation you will find but break it down and think of the possibilites.

This man made a feature length movie in 5 months.    Imagine taking a year, sprucing up the models and modeling.  It is quite possible to make something awesome in less than a year.

 

Watch and learn.

Here is another one of those videos combining 2d and 3d animation to get better results, especially if you are not the best artist and want to try 2d.

If you are not the best animator or you are the best at it refrences can be awesome and helpful.  We talked about using 3d as a reference but you can use an actual person as well.

Here are some videos talking about animating using references and still drawing as well.

 

 

I think there are ways around it by using 3d or CG type stuff but personally to do these awesome 2d things I think you need some skill in drawing.  You be the judge.
