Command hub building design study for the game Space Tales

We are developing our first game at Saigon Dragon Studios! Being huge Real Time Strategy games enthusiasts, and having significant experience as an art studio on this genre, developing an RTS was the obvious choice for us. Space Tales is set in a retro futuristic universe.
The base building mechanic will follow a grid expansion system with classic retro sci fi glass tubes. You can find here some of our first building concepts.
