Not that good
Sorry mate, I didn't find this flash very good. There were a few things bothering me;
- Choppy 3-D animation.
- Character design was not original at all
- Way too linear battlescenes
If one of the yellow guys got shot, the death animation looked the same every single time. Furthermore the very first battlescene was just some guys standing and shooting, nothing spectecular or interesting. It was boring, even.
The only original character design I saw was that from the bad guy. Although it wasn't spectecular either.
Furthermore I think your primary improvement should be the animation itself. It was very choppy. There were a few smooth parts, but overall you could easily see you simply lined up several "drawings" in a row.
The series isn't bad, trust me, and I would never be able to do what you did, but in my point of view it just isnt that good.
