What is this anime?

I found this wallpaper at a point and thought it looked cool. But now I am really wondering what it is. Mainly because at the time I found this anime I was stuck on Eureka Seven and didn't want to want a SINGLE other anime. I am pretty sure this isn't concept art too. So please, if you can. TELL ME THE ANIME!!!

It doesn't seem like its from an anime. Its a project called Pixiv Fantasia.
