Lol she's obviously slim, but for a figure skater, I don't think it's verging into danger territory as of now. Some girls are just built that way
I agree, what she needs is more power or else she'll be stuck w/pretty princess programs. Not to say that there's anything inherently wrong w/them, but greater power and projection would allow for not only more variety in programs, but also higher PC's. One thing that has struck me in people's live reports of Carolina and Yu-na is how both skaters have strong on-ice presence that just draws your eye and keeps you captivated, mistakes or not.
