Use a sketch layer and onion skin.

You can’t always rely on tweened animation and simple blinking cycles... Sometimes you have to get into “real” frame by frame animation. Such is the case whenever something turns around such as the head for example. This is where animation gets more time consuming. Now in full animation, a head turning around may well require 8-10 drawings including a subtle anticipation followed by acceleration, deceleration and follow trough... but limited animation allows you (even encourages you) to be more direct. 2-3 drawings will get you trough ANY two key positions. All you have to do here is draw the first and last positions of your action. Then add a frame in between. Then draw the basic shape with onion skin enable. Then add the details. If the movement looks rushed, you can add frames either between the 1st and 2nd frame and/or between the 2nd and 3rd one. And it’s not always as easy as it looks!Don’t forget real life is boring so that means EXAGGERATE! Let your animation breath. Use pauses vs. fast movements. This is what gives life to an animation. Do that and it might just become entertaining!Animation Part 2:One of the trickiest thing to do when you get started in animation is the all so useful walk/run cycle. It requires quite a bit of thinking and it can be so very confusing... But once you get it right there is no limit to how far your character can go! And once you’ve mastered the technique it becomes a piece o’ cake.It’s a good idea to first start by sketching the character in a legs wide open position. Left leg first and right leg behind is one of the 4 basic positions that make the basis of a walk cycle. The others are right leg first and left leg behind, right leg at center with left crossing, and left leg at center with right crossing. The number of drawings you add between those keyframes will determine how fast the character moves. For example, a normal running cycle might require about 8 images while a slow walk cycle will have about 20 images. Keep the number of drawing even or else you’ll get a limping character.
