The design seems interesting. The outer armor is simple enough to make as it can be made from many different assortments of materials.
The innards however will be quite the task as it seems to be an assortment of wrapped around wires. I believe you can use one of those sock sleeves as a base as you wrap the wire creating this part. But once that's done the rest should be straight forward.
When in doubt, just take the next small step.
With that next step take a deep breath. It calms the mind.
When the mind is calm you realize the best is still yet to come.
