It's time to go back to animations roots and the job of lead animators. 

Brief, but important history lesson

In draw-it animation studios, the lead animators job was to draw 'key frames' to tell the story. Then, all of the junior animators drew the frames between the key frames. 

This is exactly what needs to happen when you animate by hand now. Like a cinematographer or director, planning each 'shot' and then setting the key frames will make the job much easier. Carrara will draw all of the 'tween' frames for you and then you can merely fine-tune as required. 

The next important thing, since V4 and M4 are realistic, is to pay attention to center of gravity for the character which is usually over one of heels of the body. 

Finally, when you get some successful sequences, save them as animation clips so you can combine and exchange your own animations to create new ones. 

Post more questions as you have them.
