Hi, you sent me a visitor message ages ago and I haven't gotten to it until now...
"Hey! Couldn't help but notice you're a big fan of Blue, too! Is your avatar image from Pokesho, because I've searched the entire site and can't find her in that pose?"
The answer is, yeah, it's from a Pokesho image. It's actually from a larger image featuring all the female protagonists--I edited it to give it transparency and such, so the background is removed.
