All Zbrush. Quite like the hard surface tools.
Holbien Watercolours + LAMY Safari pen
I have a new LAMY pen... yeah those ones that exist inside a glass cabinet signifying that they are somehow more superior-er.
The flow is really something else - I'm guessing catered for connoisseurs of calligraphy. It comes out dark, and stays dark even if I applied watercolours on first.
Not to mention, I sat in the rain doing this. The drops splattered my page but it gave it a nice effect.
Here are some other sketches from the day after the jump. Started off at Starbucks (as you do) and then some heads on the train back.
