nice light and angle. it held up well to the crop. some nice detail left in there. i'd give it some CCW rotation by leveling it with the darker wave? it throws me off a little.
Very good HA, eye contact and wing position. Wonder if did a little more selective sharpening of the bird could you bring out a little more detail and texture:).
Like your tech info Got the ISO high enough to increase the shutter speed and give yourself a chance !!! Exposure wise its a little over I tried downloading and bringing detail back but was unable to do it for all areas .. however all is not lost !!! You could clone some texture from adjacent areas at about 70% ... looks good !!
Pose wise you want the wings up or down Bent wings will always be problematic. One thing that looks good and is important is having a clearly visible eye which you have !!!
Next time you go out make a perfect exposure and set the values in manual !!! Will be fun shooting with your new lens !! Remember to set the close/far properly and prefocus for faster acquisition !!!
I have tried again: went back to RAW & decreased exposure on the tern. Rotated CCW a bit. Was more careful & selective with NR & sharpening, and lightened around the eye a bit more
