Wow!!! I really just love your picture. The moment i saw it, it gave me the sensations of humanity Orianna lacks, I will be the hapiest LoL player if this gets to the store as a skin!!! I am writting some fanfiction of Orianna, would you mind if I use your picture in the story?
I agree with Inqubus-verseum. It's hard to see the ball at the first glance. Maybe a little brighter tone of grey or some reflections would highlight the ball.
I really like the framework of her skirt and that light, reaching out from her core of energy as well as her sad lonely expression. Gives you the feeling to hug her, well... probably you would be dead before u can touch her, wouldnt you? Overall i really like the whole atmosphere and lighteffects of the picture. Great work!
