I made this walk cycle for my summer class in CGI design. I find i am a better animator than modeler though, so I decided to just take someone else's model and run with it. I find animating in 3D to be drastically easier to animating in 2D, seeing as I am able to manipulate the model easily, and know how to play with the keyframes. You don't have to make all the inbetweens if you know how to manipulate the model correctly, despite what some people make of it.
This sneak was used in my short film, The Bungle.
Oh cool thing! What program do u use?
I am an animation student currently but I haven't really worked much un 3D programs...since I am barely taking a 3D class. At my school we usually use Maya 2012 I think
