The ECMA's standards say this:
Broken- Broken marked mice may be shown in any recognized color. They have as many colored spots or patches as possible on a white background, even in size, sharply defined, and distributed irregularly all over the body to create a pattern that is pleasing to the eye. A face patch and opposite ear patch are strongly desired. Rump patches should be halved or minimal.
(Quoted with permission.)
I quote the ECMA because it seems mid-way in between the AFRMA's and the NMCs in what it requires on a broken mouse. The spots, to me, look poorly defined (in other words, not "sharp") and there is not only a missing face patch and opposite ear patch, but also the rump is way too heavily colored.
Not to say she isn't an adorable and unique (and cute) mouse. She is and if I had her I'd probably keep her.
