I guess it's a little late to respond to this... there are two words you need to commit to memory: REFERENCE and PERFORMANCE! This animation looks robotic because her movements are far too precise and utilitarian. If you tried to adjust your glasses just by throwing your finger in a straight line towards your face like this, you would poke yourself in the eye or nose. And moving your hand that fast with the rest of your body static would only be possible if you were specifically trying to be rigid.

If you try this movement yourself in a mirror, you will see that there is a LOT happening besides the utilitarian movement of the hand and outstretched finger. You will find that humans approach their own faces very cautiously, because we have a lifetime's experience of accidentally jabbing ourselves, and also because we can't see the action as we're doing it so we have to "explore" with our hand a little bit. You might even shift your weight a little bit from one leg to the other. There are myriad other little details that you would discover if you studied this motion a little more in the real world. And they are all important because they make the character believable. Remember that animation is ACTING more than anything else. It's a form of pantemime that permits unlimited control, so take advantage of it!

You've got a pretty large character, so its hard to say what would be best.  I (and many others) have found that using a tablet to block out color blobs in an animation program works really well.  You can mess with the timing and basic motion a lot that way, without wasting too much time trying to get the linework just right.

Umm... Firefox. Looking better now, maybe add a few subtle highlights or shadows to the hair in the back? try to add some more form to it.
