A Study of Coloring in Medi Bang

I experiment to color using Medibang. 

At first, I color the the clothed with red and then I set the layer into overlay. 
And then, I color the skin.

I color it first, 
and then set to overlay.
And I add another color below, and I set the intensity by pick dark grey to grey. 

For the face, I use blur tools and then smudge tools.
For the hand, I use airbrush hard, and then normal airbrush. 

After that, in sketch layer, I erase some shading line.
