Wait you did this in flash?
This looks choppy, rough and visibly unfleshed out at times, but goddamn I love this. While I feel like this sits in a stage between animatic and animation, you can still get a good sense of motion. The character designs look swell and several actions are well executed.
I particularity like the part where she tries the lift up the thing, but she loses grip several times and leans back to counteract it's weight. You created a good sense of gravity and illusion of weight, good keyframing and positioning.
Keep it up!
