Sorry, but it wasn't very good.
The music was irritating and it didn't loop well, there was no sound effects when the guy shot his gun, there seemed to be no real storyline or plot, and the graphics weren't all that great.
Some of the animation was alright though such as the bird flying. (it looked good for someone who is new to using flash)
Well, practice more on flash. Don't give up because you will improve over time. 2/10 for now.
