This is the vector I made for Kelsey and her wallpaper (which you can see below). She changed the vector because it needed to blend in better with the background - and I made it "basic" because I didn't know what she had in mind ^^"

Of course, I brought my own touches to this vector (read: changed it so you don't know the anime unless it's written somewhere on it ), like the eyes and the hair. I used an image of Yuki as reference, to get the colors right (especially her uniform and eyes). I don't even know the true color of that scarf but red looked too strong so I stuck with some orange.
Reference image - the second one on the page.

So, as usual, please credit me if you use this vector. And drop me a line too, I'd love to see what you did with it ^_^
