Creating Hands:

Firstly, create a cylinder, then increase the segments and also adjust the point position. Adjust the location of point according to reference map to. And then copy the fingers. Adjust the location of the length of each finger. Create a box, adjust the size, and increase the number of segments. I will accord with the reference map to display the box. And then link your fingers. Choose the bottom edge of the fingers. Choose the bridge edges to link each finger. Adjust the location of the points. And then will combined box and fingers, select attach. And then select the target weld to weld the points together. To adjustment every point of the hand, delete redundant points. Finally add a modifier Meshsmooth, the hand model has become more smooth.
After complete of the model needed to connect each part and then delete useless side. Another is the most difficult thing is to modify the model. Because this reference map is more anthropomorphic, and I want create cartoon-style, so there are many areas need to change. Reference map is used to make the outline of the human body model, after that it necessary modify it according with my own ideas. So I spent a lot of time to change the model to make it smoother.
