This drawing is done in my smart phone. I am using Samsung Note 5 which is very compactable for my drawing skills. Also Am thankful for Sketch Android drawing app. This drawing is a figure drawing. I model my left hand. Here is some screen shots you can easily understand My drawing style.
This is initial drawing I made in pencil mode. See more reference lines in this screen shot.
In this stage I apply some basic colors by paint brush tool.[vineetha]
Some details are made by blending tool. This is very easy to mix colors in this app. I am facing only one problem here. That is the canvas quality is very poor. So if we are zooming this canvas, it will become more blur and will show pixels.. But its OK. Its performance is good.
