Well here's my entry for your challenge Cloud-san. It features Rinoa Heartilly from Final Fantasy VIII but the render is from Dead Fantasy 2 which is awesome by the way. I am a huge fan of Dead Fantasy and Monty Oum's work. If you haven't seen his work on Deviant Art,here's a link to his profile and galleries:

His work is really amazing if you haven't seen it,I would highly recommend checking it out. He is an amazing artist. Well anyway let me say a bit about this wallpaper.
The wallpaper is of Rinoa Heartilly in her Angel Warrior form and I found the renders on Deviant Art. I love that site cause there's so many amazing artworks on there. Well anyway for the background I faded and overlayed some sky pictures together with a starry sky and a city. I hope it looks ok. Well I would like to dedicate this to Angel Zakuro for being an amazing friend and to Cloud-san for making this awesome challenge.

EDIT:On the wallpaper I accidentally spelled Monty Oum's name wrong in the part where it says "Rinoa pngs rendered by Monty Oum". I misspelled it as "Momty". Sorry about the typo. It's spelled correctly in the description however.
