Good day.
I am trying to model this for some training in Moi3d then Blender then 3dcoat.
But I am stuck with the arms what would be the best and easiest way to accomplish this?
The body, head and feet went quick...

I made something that look like the arm with some circles and sweep...

File attached.

Thank you!
