At the beginning, I need to have an idea about composition, the design of color and value; of course, most important is the idea for the painting, these take a lot of time for me sometime.
Then I will mark some key spots for the proportion. When I continue on the painting, I will just focus on one part of the painting each day, and try to finish the part as much as I can. I find this is the best way for me to paint a live model because next time she may not pose the same thing for you :) but I will still need to come back adjust the whole painting later.
I will try to do some set up for next time by the end of the day, therefore I will have some chances to apply different techniques on the painting later.
Tendai is a beautiful African girl, the texture on the canvas showing through her face added a trace feeling of wildness to her, I like it.
