Some constructive critic
Let's start with some negative points....
- Short: What can I say about this?....It's just short. :)
- Soldiers "beaming": Sometimes soldiers disappear before they reach the end of the screen. Or they "jump" a little to the right or left. Keep a closer look on the onion skinning. This should fix it.
- Tweening: In the second scene there's a soldier running from right to left. The background has a nice "up and down" but your sprite is running in a straight line. A motion tween along a path would make it look better. This way your tank could be riding the dunes instead of flying in the air.
- No story: A story is not mandatory, but definitely gets you a better rating.
- Auto-Loop: Make it stop and add a replay button. Auto-replay makes every video look worse than it actually is (except SOME videos when the auhors use it on purpose)
Now up to the good points....
+ Sounds: You added sound effects and they almost always match. Nice one.
+ Music: Good choice, but you should credit the music.
+ Animation: Besides the "beaming" mentioned above, your sprite animation looks good for a first work.
Finally, it's a little sprite movie, but nothing outstanding. A good first step, but now you should keep on practicing. NG has many tutorials, maybe they help you. (Even I learned one or two things there, and I've never finished a flash)
