Listen!
I loved your ability to tell an action packed story, man. I think you have a real nack for making a very "epic" looking film. A very nice action style and it works nicely.
Here's the thing. To really become great you need to now focus on raw animation. No more TWEENS unless you're using them to pan around dynamically. The way you told your story was awesome and it nearly outweighed the lazy tweens. I think this is the reason your movie did well. Imagine if you animated it more stictly, though. What you need to do is draw keyframes and throw in some dynamic poses and altered angles. Distorted depth and the works. Learn to make your perspective and poses, then animate those keys. Once that's done, inbeTWEEN them... not using TWEENS :P
I liked your storytelling abilities but I think you need to work on your animation and have more fun with that aspect.
Hope this helps, dawg.
