I forgot I had this picture on my DA (in a folder titled “Artwork From Others not my work”).  
My friend, who recently got a DA (RoxieTheDerp) drew this for me a while back when I was still trying to decide on a design for Umbra. Thusly, Umbra doesn’t look like this anymore, for the most part, and this is just a concept for a while. The hair is different, she’s another shade of purple, her cutie mark has changed, etc… This was a trial-run, a rough-draft, a concept of her design. Still artwork of Umbra, regardless.  
She didn’t upload it to her DA after making it. But she did post it to her tumblr, so I’ll link that.
