Where to begin...
First of all you should think about posting this in a pure video-portal rather than on Newgrounds.
The video was a bit laggy for me, you should really add a preloader if you insist sticking to the flash-format. Also the action was quite boring and rather short for that size. If this is advertising for a clan you shouldn't show so much 'everyday-routine' but rather awesome and amazing stuff you guys do. There was no information about what makes you special and not even a group-picture. Last but not least: There was no url, no contact info, no logo. Even if I WOULD BE interested in joining your clan, how would I make a first contact?
I started out expecting nothing too great and still got disappointed...
