I think thats completly possible, but that marine must be really lucky, or has alot of skill, or both. Id just cripple her and while shes still alive id stand on her head shouting "yah I did it! you hear that everybody I did it!!!" LoL.
I love it.. the teeth, the neck to the crippled arms. Well done. But (and theres always a but) a couple of things seem out of place or off to me. Firstly the blood on the rear dome of her head glows like Predator blood, yet the blood in the lower right corner which isn't illuminated looks pretty spot on. Hrmn actually thats pretty much it. One thing i would like to have seen is the inner jaw flopped limp , but i understand the inner jaw can often throw off the entire lighting of the teeth.
