That shoulder is amazing! You just seem to produce nothing but new and amazing work, keep it up man!
One thing I will comment on: the smartphone in forearm. A great idea and all, it's just that you say your armor has been 'discovered' and has a very rusty, broken down look to it. In my personal opinion the smartphone may look a little out of place. Maybe putting a piece of cracked plastic over the top to give the appearance that it has seen better days (I don't know how that will affect the smartphones functionality) but it is merely an idea. Never the less, I have seen your work and have no doubt that whatever you choose, it will fit in and continue to delight and surprise us. Can't wait for more
