I get it if it's your first, and you got to start somewhere... Take a little more time to show something. Not that you did terrible. For no more than it is, it's not terrible. Unfortunately a tank firing onto a building has only been done about to death, in real life as well as animation... Keep staring at this and you'll be able to think of something interesting. Try not to take this too personal, and just think... stretch out that mind... I know you can play with it and find something well beyond this to display to the world.

Tip : If an artist can evoke a visceral reaction in his/her audience (love it or hate it) then the artist has done the job right. Art's not for the faint of heart, weak of stomach, or light of nerve.

Tip - instead of having the "Mission accomplished" writing slide into the video, it'd look more effective if it was slapped right onto the screen, and then the badge appears. At least, that's what many shooter games uses to animate the success pop out.

And also...the bullet has teeth!
