Years late, I know, but lolicon is not an age group, it's a style. Oshino Shinobu is hundreds (thousands?) of years old, but she's still a loli. Adding big breasts doesn't completely negate the style either. Bodily proportions like head vs body, legs vs body, hair length vs height, eyes vs head; a lack of hair, blemishes, or wrinkles; innocence and frailty; these are all qualities of lolicon.

Then again, it's all semantics. Without any background knowledge, however, this sure looks like lolicon.
