Some pretty nice shots there. Some of them, like the single strawberry, ladybugs, that dew-tipped. . .whatever that thing is, and a couple others could use a bit more depth of field. f/4 is often times too wide an aperture for macro shots. It certainly worked in some of your photos, but you need to decide what your subject is. Now, your subject doesn't have to be an entire object. . .it could be an eye, a wing, just a couple petals on a flower, or even just a portion of a petal, but that one thing that is supposed to draw the eye into the photo should be in focus and not mostly faded into the fore or background.
