@cloudguy: The original is really good but like a lot of anime it finished long before the manga, this remake is a faithful adaptation of the entire manga. You don't have to watch the original but it is worth watching eventually if you end up liking the remake and want to see what was different.
@x_woman: You don't have to reply me, requests are handled when a wiki mod sees them.
This specific image won't work well as a default, it is too tall and when the site auto crops it it will look funky and when shrunk down to thumbnail size the character won't be recognizable because of the background and overall small size of her head. Also comic art is preferred, as is official art that comes from an official source rather then someone that hasn't worked on the character in an official capacity (that image look like fan cgi).
