Very much like the first two.
I have mixed feelings about the grass in front of the subject. I can see the point of getting a clear view of the subject. But on the other hand I find I have to be careful with that sort of improvement (and I do do it - I have tweezers and scissors in my bag for that very reason). However, I find that sometimes a shot has some "character" (not quite the right word but it'll have to do for now) because of the random placement of elements, including sometimes ones which impinge on the subject, character which disappears when I tidy up for a better shot, and which actually makes the shot seem rather bland sometimes. (The "character" here might be of the "hiding in the undergrowth" type of thing.) So, perhaps take a shot or three without changing anything to begin with, and then try for a tidied-up version?
(And sometimes I try tidying-up a shot where an insect or spider is the subject - silly really, hardly ever works, as things on the ground are often interconnected and pulling one bit here joggles something else over there and hey presto, exit subject in an instant.)
For the fern to work for me the half frond that is in focus would need to stand out more from the OOF fronds above and below it. (I don't know how one would achieve that, but someone else might.)
In the last one, it's a personal preference, but I try to avoid images in which there is an out of focus element nearer the camera than the subject and obscuring some of the subject. It can work, if there is an element of "framing" about it, but in this case the front OOF element is, to my eye, too much in the middle of things, getting in the way, a distraction.
- Im still trying to find one
