Eerie Artwork Pops Up At Tango Gameworks

Shinji Mikami’s new studio Tango Gameworks is developing something for Zenimax to publish, but they haven’t revealed any details about their project. Maybe this art work is a clue?

These illustrations were drawn by a O-sensei (tagged as "teacher-o") and shared on the Tango Gameworks blog. Any idea what these peculiar looking bugs and ghastly creatures could be?
