So just out of curiosity and for comparison purposes, I looked up where MaTTcom stood when his skins were made into real skins (Astronautilus and Pool Party Ziggs) and in terms of upvotes, Firedancer Draven is only 330 upvotes away from being where Astronautilus stood, and only 260 upvotes from Pool Party Ziggs!
Let's hope that's a good sign... There are plenty of other skins that have had more upvotes than that and haven't been made into real skins, though, so while it is a good sign, it's not a definitive sign by any means. Only time (and support!) will tell 
Edit: Oh, another interesting note! Apparently Riot made his skin in 5 months. (Going by the date he posted his threads up to when Riot announced the skin) So I thought that was really cool, and definitely good for him :3
While it's unlikely that I'll be that special, I can hope, right? Heh.

Edit (again): On a less happy note, I got another downvote on the poll putting the "nah" vote at 3%. Sadface. Ah well, at least 97% of people still like it; I can't win them all, and you guys have been pretty amazing for me to even have numbers as high as I do~
