From the photo data, I would say that shooting at f/1.8 is overkill. A bright day, a model who is not moving much if at all, and ISO 100 says that you could reduce the aperture size to increase depth of field and get a much better result.

Why?  You don't know what effect the OP is trying to get.

If you were shooting in low light, a larger aperture would make a bit more sense, but still is not optimal for a subject that is not all in the same focus plane. Try shooting the same subject at different apertures to see the difference.

That doesn't address the issue.  What is unclear is what is the focus plane.  If he had asked "how do I get the whole of the girl in focus" then yes, the answer if f/8 or thereabout.

You don't mention what mode you are shooting in - A, S, M, etc. - so it is not possible to know just how you (or the camera) came up with the combination used. But the aperture has definitely caused a DOF problem!

It really doesn't matter.  Exposure isn't the primary issue here.  The camera has pretty well followed the "sunny 16" rule.
