Pull IT Animation TesT2

Here is my animation so far for my "Intro to animation" class. Ive done a little bit more from the last time I posted this a week ago or so. [link]
I did some of the inbetweens at the begining umm theres like one frame in the begining that i wanna change it doesnt flow right. The Timing is alll wrong, this is not the timing im gonna use when its done.
I was running late for my next class but i wanted to film what i had so far so i was rushing and didnt bother trying to get the timing down.
What else.. umm.. the end is.. not finished.. my background isnt animated yet, theres supposed to be a fly in the background at the end that comes down slowly and lands on the lever and switches it on and so at the end the guy is reacting to that.. and well.. um.. yea..
What better way to end an animation than by killing off your character.. no really, after you have to draw something so much you really want to kill em XD
I hope to fill in more gaps tomorrow in class.

Oh BTW, in the end... you dont see him... pulling the trigger, i plan to fade to black as you see that last frame, then in full darkness after a pause maybe after an end credit, you hear the BANG XD
