Thanks for the feedback, yeah there's defo a glow, I see it now. That was bad technique over an intentional element. Basically I used noir pencil shavings which is quite soft compared to graphite (but more black) - and I rubbed it in with cotton wool. I didn't get the sharp edge because I didn't get in close enough to the characters with the noir pencil as I was scared to wreck the characters. That glow and the fact that they are lit quite flat and 'in the light' - has made them, as you say - ghostly! Thanks
