#2 and # are beautiful; I question your choice of focus-point in the other two. Our bluebells up here look like they are going to have very good season but have not reached their peak yet.
Not sure in which two of three pictures you are questioning the focus...
In general choosing the focus in these images has not been am easy choice, apart from where depth of field has been minimized deliberately to bring attention on detail rather than the whole scene.
While I was shooting I mused that it would be an interesting subject for experimenting with tilt and shift, I think I'll give that a try next time I go but I need to have plenty of time for that.
