Yeah... Some actual animation would be nice
Either that, or actually finish your series, then follow it up with this. As is, it's basically a resubmission of your first animation. Why do that when you can promote your WHOLE series? =)
But seriously, as some people have mentioned, the mystery buttons should say coming soon, or you should mention that it's not yet complete somewhere (if you don't like the advice about submitting a complete version of this after your series). Not to mention, you could name your series and link them to each other within each animation without the need of a "dossier" (i.e. on part 2 you say "Watch part 1, Snowblind UC" or something like that).
Not to mention that no one will be likely to refer to this submission... It has a low score already, and you might as well link the animations together as i suggested above.
I see what you're trying to do, but I think there are probably better ways... Good luck with your series =)
