Hi everyone!
Im David, and it's the first time I do a challenge from here, I hope all the best to you guys!
I have made some sketches for the underground city, the idea is to make some rudimentary port city, made of wood platforms and "rubble" materials, surrounded by gigantic ancient structures (the ruins of the old civilization), making the new settlement look small. Feel free to say wich one you like the most!
Also, if anyone wants to see some of my work, here is my arstation: https://www.artstation.com/artist/davidfranco
