Lego man

Hi,

After a very long time, I decided to start a project again.
I’ve chosen to make little legoman thingy, from one I own myself.
It’s a dude on a motorcycle, which will also be modeled.

But after an hour or two of work, I got stuck.
The arms! The horror!

I just can’t figure out a way to model the complex, rounded arms.
But I’m not a very experienced modeler, so I thought maybe some of you know how to tackle this problem.

Included: some shots of my work.

Please note I’m going for an exact copy of the figure, nothing less. I know I can extrude a cylinder and rotate the lower part, but that just doesn’t look like the real thing.

Thanks in advance
