I would like that much more than Falmer. Hermaeus Mora was always my favourite Daedra.
Heres a link about Hermaeus Mora for thos ethat wish to read: http://www.imperial-library.info/category/tags/hermaeus-mora
Tbh I think that saying the mask is crab-like with shell influences is pushing it. It reminds me more of the goblins from Moria in LOTR: http://2.bp.blogspot.com/_2abjEM8O5pU/Sw49C_0a6kI/AAAAAAAAAGc/_5r5n94kq5k/s1600/MoriaOrc_v23_Pose03.jpg
I wanted to propose just a bit of speculation though: Seeing as how this series of images was found with the link, "To_delete," it could possibly suggest something that didn't make the cut for the game. Todd talked about the team playing with vampires and were wolves (he specifically said things that transform) and said it could be yay or nay. Tbh, with all of this vampire speculation, i would go as far to say that this is a trashed concept. Believe me, i always keep old art unless i dont need it anymore. Whatever this idea was, it wont be referenced for anything.
EDIT: wow, it really DOES look like that Moria Orc from LOTR. Same nose, same ears, the knees on the armor look shell-influenced (BUT ARE NOT CLEARLY, THEY WERE UNDERGROUND), the shield has a similar look to the armor. and the skin tone is waaay similar. I think i see a spot of inspiration!
