Cody,
Was this a tripod setup?
I understand how you could love the subject. I do too. The choice of 1/5 sec even when the wind is down is puzzling. That's not a good set up for getting sharp pictures. The aperture of f 16 is worth considering too. Unless one is working with a MF, large format camera or have special DOF needs, avoid such a small aperture for modern sensors, especially if you need light for the exposure. There are several reasons. First at such tiny apertures, the quality of the image is degraded by interference with the edge of the aperture. The light, as a wave front, is perturbed and ripples of disturbance impair the clear image that the lens would otherwise throw on the film or sensor. The other point is that one needs a certain amount of light to properly record an image. In this case, one could get the same amount of light with f5.6 and 1/20 sec and get a far sharper image. Many lenses are the sharpest closed down a few stops and don't get better by closing the aperture.
