Constructive criticism
Listen, I'll start with what I liked. I liked the graphics cause it was something you dont see here on newgrounds all the time. I liked the character models, and I liked how the scenery was setup. You did a great job on putting the visuals on this piece, I feel this is your strongest point.
As far as the plot goes, its rubbish. A comedic plot like that was fucking sad, the least you could have done was make something that wasnt surrounding such a stupidly serious idea. But it wasnt the worst plot line I have seen either.
And as for the sound, with such a graphical piece visually, you failed miserably. At least could have spent more than 15 seconds writing such horrible dialouge. For Christs sake you didnt even put in the sound effects from the guns n sh1t. Also when the video repeats its silent, and I think I liked it more silent than with sound.
Lastly, the humor. I didnt find any of that funny, just sort of stupid. I commend you on having the balls to take the "collumbine issues" and "trying" to make it funny, but my freind you didnt pull it off. If you had more of a serious approach to the movie "Sonically aka SOUND" I think I would have really liked what I saw. Just remember that if you want something to be funny, the idea itself has to be funny.
I hope you take what I have said into consideration and I hope you continue to work on your art. Your concept was heading in the right direction, and with a bit of practice you will have front page all the time.
