I have reverted to sketching during my tube journey to work. Lunch breaks are being used for writing my new comic, so no tree drawings for a while.
This was blue pencil, and I have tried to preserve this in the scan, rather than threshold it. This is why the other side of the page can be seen.
In other news, Thought Bubble 2013 exhibitor tables sold out in a few hours. I missed out, so will enter myself in the reserve lottery. It shows what a good reputation TB has gained.
