A very decent animation.
For what I was first expecting this was actually very good. The animation was alright and the guns and stuff looked good. You could work on your art a little more though. I've said this before a million times, I'm a horrible artist too, so what I do is either use sprites or trace. Stick figures are noobish, and so is not having a preloader. Newgrounds kindly offers a free preloader you can download! Use this until you figure out how to make your own.
Another thing is the audio. The sound effects seemed a little off to me, this can easily be fixed, but what really bugged me is the voice. I know you can't help it but you sound like...well 12. It really makes the entire animation look much more nooby if you can tell it's made by a 12 year old. There are many helpful people out there who will do voices for you for just a little credit. Don't be shy. Ask around, having a voice actor do the talking in your movies makes you seem professional.
Good luck with your next animations.
