Upper right arm done - apart from cables, again due to the fact I think it would be easier to pose this before creating them. Going to leave it till all the arms are done then do them all together I think.

Moving on to the lower right arm next.





Edit - Dame it - forgot to do the pads on the fingers so not finished - oh well - very close. Also added a plan for the cables so you can see what some of the parts on the model do.
