Machine Line art

Line art of the other days "Sneak Peek", what's quite ridiculous is that most of this will be in shadow around the outside in the finished picture!
For now I'm just calling this "The Machine" so as not to give away any plot details.

Going to work on the shadows, then flats (in grey tone) now.
I think I'll take a break from this tomorrow and work on something different, then back to this at the weekend.
