Not bad
I thought this was a fairly good picture because it did seem like you were trying something new. It didn't involve robots or anything like that. I was expecting it to be a picture of some sexbot. The robotic limbs are a really nice touch too, especially with how they make her seem more cybernatic. She doesn't really seem like a character that would be in a parody, however. I kind of wish I knew whoever Chell was.
There's so many art pieces about stuff that never got off the ground. It's great we always have these images to help us out on the way. There's just a great sense of emotion put into this as the character looks so full of joy. Not your best detailed, but still good enough to recommend. April O'Neil showed us orange jumpsuits are good for hotness.
