Hey, no worries! I did the same thing with my Bulbapedia/Bulbagarden and YouTube usernames too. And if we're talking about being unimaginative, my YouTube username was SO unimaginative that it got old an eternity ago after I lost interest in the thing I based it on, but now I'm stuck with it.
May I ask what month is your birthday in?
Also, I must agree with Vulpix and saying that your avatar is really cute! I think I prefer the previous, hairless version, but this one isn't that bad either! While Cresselia isn't amongst my top favorite Pokémon, I still like it and think it's really pretty-looking. (Plus, Psychic is one of my favorite types, so that helps.)

But still, that’s cool!
