I never noticed this till now but I just realized it once I saw this tonight. The winged women in this mural are all reaching toward the light on the ceiling of the bottom level of Wyrmrest temple.
BUT the Titans and Titan artifacts are all based on Norse Gods.
Also no species we've faced yet resembles Angelic figures (Winged humans)
If someone can post a picture of the ceiling on the bottom of Wyrmrest that would help the discussion. I'll figure out how to post an image from my computer later.
So do you think that this is an clip art by a lazy artist or a hint of things to come in the universe of Wow?
