I've seen good before...
...But this was just amazing. I never liked the Joes Zombie series, but I did like most of your other flashes, and I love your stuff on Explosm.
Pros: ...Exquisitely worked on. You combined everything I've ever seen in a flash (and I hope you used a vCam to make it easier), for 3D effect, and for scale. The scale effects were amazing.
Cons: ...You had the revealing conversation plot device in there, but that's all I noticed that I didn't like much.
You should do this professionally.
