Got potential
Obviously it is hard to do some kind of animation about dancing to Dragostea Din Tea that is original and since you just picked up a pile of dancing bits from the internet, originality was not what you were going for.
However, it was a bit of fun; you did find and use a lot of different dancers and we do have a special place in our hearts for Numa Numa on NG.
The potential would come if you:
* did something fun and interesting with the backgrounds.
* You could use more of the screen instead of just the top left side.
* You could add a couple of sequences of your own made of Newgrounds characters.
* You could even get hold of the Inappropriate dancer that the early Clock Crew movies used- which would reel in some old time CC support for the laughs.
* Try talking to the Review Club, admitting that it isn't great , but saying that you might redo it better if the ideas seem right.
*Preloader, even if it doesn't need it. Always
* Credits of some sort IN THE MOVIE. Always.
* Stop/replay button . Always
Also, never criticise reviewers for their writing skills. You put your work up for view/review- they are doing that for you. They are not asking for their reviews to be criticised, by showing your work here, you are. Even if their work is negative, it is still an evaluation of your work and may provide much-needed info.
