Excellent work mate, you concentrated in having a sharp eyes and bik.
I know that converting the original images to jpg and then reduce the size for the internet it is tricky and a lot of info it is lost.
If you allow me to made just an observation it will be on the first image which IMHO it is just a touch to sharp'.
I do not know which kind of PP software you have but if it will allow it I would do a selective sharpening making sure that eyes, big and claws are just a tad sharper than the body.
I love the BIF images nice action and posture on them.
