I feel like Ymir's body would be cold, but Christa's body would be there to warm her up :3
Actually I feel like it would be the opposite, with ymir being a titan her body temperature is probably higher than most. Plus steam comes out of her wounds.
I didn't really like the art too much. It almost looks.. unfinished? I mean as far as I can see ymir is supposed to have a natural tan and they were both pale as a ghost. Meh
If they are going to die than I would want them to both die together, I know that sounds messed up but too me it's kind of like a romeo & juliet sort of thing. Them dying together is tragic but also romantic in a way.
I liked this a lot. I have a lot of insecurities about my body too, so I didn't go to the beach at all this summer.
Well good thing I don't have a flat chest but still girls worry about stuff like this a lot. ^_^
