So you should be blocking now. A lot of animators use this method of stepped keys to block out their animation with solid posing and all the major details such as facial expressions, hand gestures, eye direction but NOT lip sync. They check and recheck for strong silhouettes and keep honing their timing until it seems perfect before moving forward.
Here's a great example of blocking from Kevin Webb.
He describes this video as the result of a day's work. I think you will agree that was a productive day indeed.

Here's the final result. Notice all the beautiful overlapping action - it's not just pose-to-pose, he's layered on texture in the timing and made everything fluid and lifelike. 14 seconds, no textures, no lighting, no background, no bs. Just great acting and great animation.
