WOO!!
so like, hooray you're officially my HERO!!! I've got some constructive criticism though, if ya want it...
Pros:
1) AWESOME MUSIC!!!
2) my favorite part was how the animation actually synced up with the action of the characters (example, the four count scene of the dinosaur coming after that one dude hahahaha!)
3) great animation, color, style, detail, etc. it's unique and i really really enjoyed it
4) i actually LOVED the fact that the piece had no sound effects because all that was needed was the snappy music
5) enthralling...that says it all
Cons:
1) too many characters? after while I stopped trying to figure out who was who and just enjoyed it
2) a little to "fast" for the eye too many times...but like i said, the timing was gorgeous so no real worry
3) in this piece, it's great...but be careful with randomness because it's a double edged sword...it can be funny or horribly confuse the plot...but you're very talented, so again, no real worry
4) NOT ENOUGH PEOPLE HAVE SEEN THIS FLASH!! yah, that's a con, hahaha
Overall, GREAT JOB!! A+ for you, keep it up!
