Needs some work
I can't stress this enough; You need a preloader for this one.
The lack of story is forgivable with some of the action, but with time and practice, you can smooth out the graphics and have a better looking piece to submit.
It wasn't totally bad, it just wasn't good enough to be something that would be seen as enjoyable after the first viewing.
Just keep up the work and you'll eventually have something with this one.
