Fairly good.
And yet we have a new Dumbassdude short, "DD finds a gun!"
In my opinion, it could be better if you took more time on it, you have enough potential.
The intro still looks a bit... imperfect, try to make the animation smoother. Also, seing the same background over and over again.
The movie itself was fine, the story was...ok. But the action was really slow, it can become a boring :(
The sound you used is good, but maybe you should keep the background music a bit lower and use FX sound.
Other than that, nice job! Keep improving!
