May I be nitpicky?
For in the first photo I would have liked to see at least one of the two flowers entirely in the frame, in the second I would have wished for the butterfly's wings to be all inside the picture, and in the third it would have been nice to at least see a little light reflection on that bird's eye that points towards us. That bird is not quite a silhouette, yet what little detail shows is too dark. And the bird is smack in the centre of the picture.
But hey, these are nice.
I am only being nitpicky, like I said.
