That's really nice! I really like the way that you drew her, she seems to be able to do anything^^ Even a device wich can create gravitational condensations by collapse of mass in sideral matter implosion
Your GLaDOS is one of the only human GLaDOS works that I like, and probably the closest to how I'd imagine her human. Everyone seems to make her hair white, but even before Portal 2, I always saw her hair dark brown or black. I like that you maintained the dark vibe, and I do enjoy that she's not fully human here. I think most human GLaDOS' take away from her personality, but even a bit here.
