And I've been working on some more background concept art. I think I'll do the backgrounds with ink, markers, watercolours and acrylics.

I was highlighting things in this with white acrylic paint and when I did a few rooftiles it looked like snow and I ended up with it snowing. Badly snowing, too much snow, it's hard to see the buildings. But still kind of nice, I think.
