Not really that good...
The drawings seemed a bit traced at times, and the animation was basically just tweening ( and not very good tweening at that. )
The jokes didn't make me laugh. In fact, they seem too strained most of the time. It was incredibly predictable.
And, by the way, cursing and cameos does not make an immediate good flash. I didn't really like how it seemed to me that you included curses into the script just to make it funny.
Next time, I suggest going over to see other people and showing them the script. ( LOZ fans and Non-LOZ fans alike. )
