Great shots!
Hope you don't mind me beeing honest here:
I have made a very simmilar shot to your first one and there is some thing that disturbs me.
Can't say what it is, maybe the gras draws too much attention away from the subject?
But nevertheless a good shot with a good composition and great details and sharpness.
Shot 2 and 3 are excellent, great composition and a great "melancholic" mood.

keep up the good work
