High Key?

[Weird Girl]

I realized today that I have been trying to practice too many techniques at one time so I am going to change that but before I realized it, I attempted a high key portrait and was wondering what you think of it? I have already established the fact that my aperture was way too high along with my ISO but I would like to know how you feel about the lighting- is it high key? Also, the composition. Thanks!

whoa, what in the world happened to my photo LOL- I'm not sure why it's all grainy and weird looking because it definitely doesn't look like that at home... Mods can delete this if you would like, no point in critiquing a terrible looking photo (unless people can ignore that and just let me know if I'm on the right track to high key or not) Thanks!
