My source of inspiration was the city from Stargate series (I'm not a big fan, I just liked the city). My main goal wasn't to replicate this city, but to create one of my own, therefore I have added some personal fantasy elements.

I have build the city entirely out of parts from the source image, created the protective aura, added some waves and got the demons silhouettes from the same waves.

A lot of work was done to find the perfect color match and to integrate lots of brushes the best way I could.

Hope you like it!
