I'll give it a go.
I'm not any good at shooting flowers so this is just my humble amateur viewpoint.
Sombody with more experience may see things entirely differently.
#1 I like this a lot just as it is.
#2 The side-on composition leaves too much of the background in the scene for my taste, and with that much background it seems like it should be further out of focus.
#3 I like this one. too. I might have wished for both bees to be in focus, but that's just a nit.
#4 This one is perfect - the best of the bunch!
#4a Seems too bright. Are the flower petal tips overexposed?
#5 The subject doesn't seem to separate itself from the rest of the foliage.
#6 This one is good, too. The focus is clearly of the bee in front, but you were still able to get the critter in the back to be sharp enough for the viewer to make it out.
#7 Very nice point of view if the background had been the sky, as in #1, but as it is, the background (fence?) spoils it for me.
Well, there you have it - my very un-expert opinionated viewpoint.
