Portal of Wat Pan Tao

yesterday's drawing:
on our way to the night market in Chiang Mai we stopped at the temple we had visited yesterday.
Since hence the kids wanted a little break we decided to rest and I thought I use the time to sketch the portal, which is absolutely amazing, while the others sat on the stairs.
I'm so thankful for my patient family...the "small sketch" ended to become an one hour study...
Lifei, I owe you something...
