Hi Brian, thanks for the file and I have given you my tweaks, however looking at the file I think the camera may have just been taken straight out of the box, so you may like to consider the following...
Based on the file:
The wing closest is sharp, but not the eye, FP was just on the neck so may be AF fine tune needs to go +1 or even +2
Aperture would have been better f/5.6 or 6.3
VR could have been switched off at 1/3200
EV needed to be at least +2/3 the file was under exposed
(as I said, get to grips with your Histogram and shooting ETTR)
WB set to Cloudy B1 it will remove the blue cast you mentioned, as it works off the Blue channel
Colour Space needs to be Adobe RGB
NOT sRGB
Turn off High ISO
Long exposure Turn off
Active de lighting turn low
Vignette turn off
Picture style - Neutral
Sharpening set to 0 not +3
Contrast set to 0
Lossless Compress change to uncompressed
Hope it helps
