hmm....... Good with a few bumps ^^;;
Stylistically it was well done, it looked nice, if flowed without being choppy, and no obvious misteaks were made.
However, like others, I would've enjoyed a little more plot, it wasn't a bad plot, and perhaps I should be thankful it had a plot, (and wasn't just some random stickman slugfest, though those can be fun to look at) I just figured there needs to be more there than - "have the female outdo the male and fight a giant robot".
But I think this plot problem could've easily been ignored if you had some exciting and nicely timed. It really does make a HUGE difference, good music can make even the most tedious plotlines somewhat interesting. (not that your plot line was tedious, just not thrilling; that's all) and finally, maybe some more action sequences, I know thats not what you were aiming for, but in that 'fight' scene you could've done a lot of neat things.
Anyways, I'm rambling, and nitpicking and crap, you may get the impression that I didn't like it, but all these errors are very small and could easily be overcome. You have great animating skills, so making it interesting shouldn't pose a problem, I mean, anyone can write something but it takes skill to animate it well. maybe watch more of the top ranking flash animations and try to take aspect of their work and incorporate it into your own..
Overall it was really well done, I really do appreciate your use of 3D graphics and you rather cartoon-y type aprroach to some parts, I didn't notice the transitions to be awkward in the least. Good work ^^
