I didn't say they didn't fit, I said they were over-exaggerated. I was mostly referring to their movement. The amount of bounce while walking is completely over the top and shows a serious lack of knowledge on how breasts move/hang/work in general. The size is fitting.
If she's running, those breasts would be fine. Her knee guards are clipping into the armor skirt. It's disjointed in that we have the smoothly shaded and shiny magnificence of her bosom coupled with the low-res blocky armor. I still like it.
