Call in the Night

This speaks to my Doctor Who loving soul. xD I may use this, once I get the time, to draw and color with a traditional medium. For it to be considered as using it as a reference, is just drawing it out and coloring it work okay? I really didn't want to change anything about it because it's so lovely the way it is. I wouldn't use it for commercial purposes. If it came out well enough though, I would like to add it to my DA gallery and perhaps even put it in my portfolio when I finally start one. Credit for the photo to you would be used of course, in both instances.
