What a fantastic piece. I really love how you can see where the clothes were torn, and how the shoulder bit sags and curls up like that, demonstrating the weight in how she's lying down. There's a lot of detail paid to the weight and thickness of the suit and helmet, such as how thick the broken glass is, and I really like how it frames her face like that. The phosphorene glow of her surroundings gives it an awesome twilight vibe and lighting.
I think the best part of this, though, is how natural her pose is. This is demonstrated in the way her fingers are curled like that, exactly as they should be. You can just feel the fatigue and sense of relief that things are finally over, or at least slowing down.
