Are you saying you want to see the concept art from the video or fan made art? I mean... if you're looking for either, you can find them already on the forums. There is a Skyrim FanArt thread and a thread discussing the update(or you could just watch the vid yourself and see it all.).
It looks like a very dangerous way to hold the blade, probably a bit painful as well but is still pretty sweet.
Typically, swords like that were not sharp enough that they could cut you just by resting on your shoulder. They didn't need to be "sharp," it was more the force of the swing that made them deadly.
