Love this design and the dramatic lighting! My only nitpick is I think the character should be bigger in frame, probably, unless there's supposed to be a kind of "helpless protagonist" feeling. There's a concept in film called "headspace", and that is that the more space you give between the top of the frame and a character's head, the smaller and weaker they feel as a result.
How'd you do this, by the way, out of curiosity?
