Her similarity to Rin was what I noticed. I plan on using multiple images of Rin in my post headers mostly for facial expressions but if you stick with that one we'll be fine because that fanart of Rin is quite different to the official images - the bust on yours is ginormous while I use the original character who has a modest bust. The eye colour looks different in yours too Evalon, so if you are okay with sticking with that one pic, I am fine!
