Recently worked out an arm shape I can live with. They look a bit "aggressive". My hope is that I can decorate the large looking triceps so that the forward portion looks like the arm, and a rearward portion looks like armor of some sort or maybe a crazy fashionable fluff of something. We'll see. Keep in mind I'm trying to keep all 3 actuators for the arm on the arm, and off the body. I think if I was building a nimble quad like Cheetah or Spot, this wouldn't work as well. I'll just have to keep motions slow and smooth.
