３。每次画的时候，模特儿需要坐多长时间？一天吗？中间有多长的间隙？

Modern portraitists use photograph as aid, besides 3-4 hours sitting, I was fortunate enough to have her sit for 18 hours.
Usually,a model sits 3 hours per day in maximum, have plenty of breaks.
４。这是你最满意的作品吗？
Yes, the original painting has much more nuance.
５。你对这幅作品有何遗憾吗？
Yes, it does have some small parts could be refined further.
