^^^ some nice captures there. Some in particular stand out.
Some however seem quite soft, I don't know if this is a subject blur, camera blur, focus issue or lens softness (perhaps heavy cropping). Obviously you get wing blur which is hard to avoid without extreme shutter speeds.
Also check compositions. If an animal/bird/human is looking/moving to the left then it is good to have a space for the entity to look/move into on the left, the space behind is fairly dead.
I hope you find these comments constructive rather than negative.
The noise (especially colour noise) in them makes me wonder if you're using lightroom 5, where it ignores your sharpening/noise reduction settings? If so, you might find you can get them looking sharper if you export with another program, or hunt down 5.2 which is supposed to fix the bug.
