Really should focus on the medical field where this will be good. It is not a junk proof of concept. yes your prototype looks worse than most cosplay but it is a working prototype. now comes refinement and design. I wish you luck.
Now do you have right and left handed prototypes? I see in the short video how things work and if you can get it tweaked I think there will be a very good niche market in the medical field for this. Better, breathable material, more refined look, and it can work. good luck.
People seem to not know how creating something goes through phases.
