The second one is TACK sharp! That’s my favorite. The third one (pink background) is out of focus. The last one is sharp too. The first one is sharp enough, but it doesn’t have the “tack” aspect, in my opinion. Just not seeing the crisp detail in the skin around the eye like you can in the second one. Perhaps viewing it on a higher resolution screen would allow you to see it better yourself.
Glad you didn’t try to edit the yellow beyond what was natural. 🙂
I’ve been shooting more and more in Manual these days when shooting moving subjects so that I can get the Shutter Speed fast enough. Av just doesn’t seem to choose a fast enough Shutter Speed. Perhaps there’s a setting in the menu somewhere that would help Av choose a faster Shutter Speed by default?
