Amazing! Ur sci-fi style is simple, but very exciting! Awesome work
If I were to build a secret facility with terrible experiments on humans, I'd build mad-science sections underground. This way they would be more concielable, and also it would be harder for experiment subjects to escape - they won't get out by simply breaking the wall.
I like the picture though.
thanks to all guys, in fact, the picture hadn´t a previous sketch, first i drew a single robot, then a room, and later other room...until the end. it was funny! all in imagination, no inspiration :)
