Look at this, two posts in one day! Don't get your hopes up it's an oldie. This is a sketch done at the same time as the Moonscape one and then scanned in. I love the quality of scanned pencil sketches. I suppose it is because on screen they are bigger than the actual drawing, it is like blowing the sketch up on a photocopier and zooming in on all the pencil marks.
I was going to start inking this tonight but as I am actually falling asleep at the computer I may give it a miss.
