I have been chipping away at this one for a while, setting up the perspective was quite a challenge. I ended up making a 3d model in an old version of sketchup I had kicking around. Particularly hard is scaling people to railway tracks; there's lots of size ratios that look fine at first glance, but actually they're way off if you stop to think about it.
Anyway, I think their heights are a bit off here, she's a bit too tall. Working on colouring it now anyway. I want to build up a few finished pieces to post in a row, since there's a kind of algorithmic momentum on twitter where you get more interaction if you're getting more interaction. But you folks get to see all this as soon as I'm finished cos you're special and great
