Really confused by this. I'll assume there are some resources you just don't know about yet and take this opportunity to fill you in.
First and foremost, any time you show anything to someone they're going to form an opinion. If you can't handle that opinion your best two options are to become wildly homicidal dictator of the world and force everyone to agree with you or, the better choice, simply not show it to anyone sense there's no logical reason for the public at large to need to see it unless you want feedback.
That being said, since this is only a test, it definitely would have been best just to keep it to yourself until you had something worthy of showing off. If you didn't want reviews and such you could have submitted it to the dumping grounds (at the top of the screen next to your account name there should be an arrow pointing into a... Dumpster thing or something) and that would allow you to show people you wanted to show, test out how it would look once submitted to newgrounds, and avoid unfriendly reviews from the general public.
Alternatively, if you did want to show it to the public but didn't want it to be reviewed and scored, you could have uploaded it to deviant art. Reviews there are usually nicer, not because the people are but because people there don't usually bother to leave reviews for things they hate whereas here reviews are more heavily encouraged, whether you hate something or love it.
By putting it here in the Newgrounds flash portal you're basically saying "tell me your opinion on this" to the Newgrounds community, which means that there will be haters. Especially since you admit this is only a test. On that note, I think the audio is a little annoying, the animation isn't anything spectacular, and the lack of a preloader sucks, but I like the way you drew the faces.
I'm a little curious, what was it that you were testing that you couldn't have simply tested on your hard drive? If you didn't want public feedback then there had to be a reason that you would NEED to upload this to Newgrounds. Kinda dumb to drop your pants in the middle of the street and then tell people they have no right to judge the buttcheeks that you're waving all over the place, know what I mean?
