Modelo4:

Besides all the defects described by @Jill_C:
I'm not sure, but your lovely woman seems to have very long arms,

The green lines show, where I would expect the elbow to be, respectively where the hands should start. Especially, her right arm is obviously not correct.

 The coat belt doesn't make sense.

The pockets on the left and right are weird:

Modelo 11:

This girl has a long neck, but that could still be OK.

I agree with @daniellei4510 that the hair could go, that is a disturbing element:

I doubt, however, that this would earn you a refusal, but it will influence the picture's success.

The image is not sharp, when checked at 100%, and that is a refusal reason.

The cloth texture is inconsistent   at several places:

The nose anatomy is wrong, or the perspective is wrong, your choice:

 The eyes are bi-coloured, but yes, that also happens in real life. But the left eye is looking at the viewer, the right eye is oriented to look past the viewer. For portraits, you normally lighten the eyes, that makes the overall image more attractive, but it is not a refusal reason. Personally, I find the ear a bit big, like a goblin ear.  I doubt that here, too, the moderator would issue a refusal for that.
