This guy gets paid for this...

Gunna have to do some acting reference so i thought i'd have a look at how the pros go about it, it looks like this guy is really annoying but the over acting totally works for this purpose. You can see how similar his animation is to what he acted, this is definitely the best way to get natural results.

So awesome, i think for the best results I'll have to try my hardest to not be shy in any way because it's the loose, relaxed approach that clearly gets the most natural movements.
