Hey sweetie  :)  As far as video games or any cosplay for that matter, I strongly believe that you should cosplay whoever you want.  I mostly feel like this because I did the whole, “cosplaying to match my friends,” thing and it didn’t work out so well.  I pretty much cosplayed a character they were like, “OMG you have to cosplay her,” so we could complete the group, but I wasn’t into the series we were cosplaying at all so it really fell flat.  I didn’t know how to pose, and I pretty much knew nothing about the character. 

So I guess if I recommend someone to you, you should really look into the character and see if you actually like them.  Don’t just cosplay them because I’m like, “OMG YOU COULD SO PULL THIS OFF!”  If I say that, then go and see who the character is.  Try and play the game their from if you can, or at least watch some youtube videos.  They might end up being a character you don’t click with at all, which you should turn down immediately.  The worst thing you can do is cosplay someone you don’t like.

With that in mind, there are so many characters in Zelda and Final Fantasy to choose from already.  If those are the games you know, you’ve already got yourself a vast library of characters.  If those kinds of games are your thing, then I would suggest looking into games that are similar (Kingdom Hearts comes to mind, or the Tales series, or even Persona games) because if you enjoy the game, you’ll probably find a character you like.
