This (digital sketch at top) was done all live on the spot. I may take it a bit further at home in the studio. It was drawn on an iPad in Brushes 3.0.
Update 2014-10-16:
Here below are two watercolor illustrations that I commissioned other artists to do based on my sketches and reference materials.
The first one is by a Lois M.
This second painting below is by Ayushi B.
