Well...
for your first real flash, it was pretty good. It just shoudn't be on Newgrounds because it doesn't have a story and it's not that long.
Graphics-The graphics were great though and the animation was good. Great gun drawings
Style-I like movies with not dialogue, just a song in the background. It gives the viewer more imagionation to what's going on in it.
Sound-Great music. Fit the mood well
Violence-There was violence
Interactivity-Replay button counts
Humor-There was none
Overall-This shouldn't be on Newgrounds because of it's lacking of a storyline and basic plot. If you use those graphics, and style again, but with a longer movie it's shure to get accepted.
