I've had serious problems with timing and spacing in previous animation test which didn't alow me to continue working on this animation and boy did it take a lot of time to just become aware of what the probem was to say nothing of how to fix it. I'm a very inexperienced animator yet.
Here are 3 tests I made when I realized what to do next. There are little (and not so little) differences in timing and spacing here that give the action a different feel.
