Thanks, some of you guys may probably find the aims of the 3D model is too skinny.
I just too excited for this ideas to build it all the ways to know it until I nearly finished it.
I was too lazy to go back redoing the walking poses again ( that takes most of the time) if I need to changes the model again.
As it is already a flatten 3D model, it not so difficult to just adjusted the edge of aim sleeve. That can be made up the illusion the aim became fit the body again.
