thank you all for your suggestions!!!! you 're all amazing people. I was really in doubt >< but i made a simple background using a black degrade . Here is the link of the drawing finished littlemonsters.com/...
I think either grey or just as it is. I think black may cause the hair to be less noticeable and it will also make her skin look more pale. But as others have stated, it's all up to you :) Whatever you think is right, is right
It's very beautiful but her skin is a little bit too white, isn't it? I think a grey background could be good or maybe a mix between grey and the same green of her eyes... =) But congrats it's amazing ;)
