Nice detail and DOF, great exposure and colors. I am not sure how you might feel about a tighter crop to have more emphasis on the beetles. I think your detail is good enough that you could. Very good as is.
8 - Very good. These colors are very nice. I really like the left background, as well as the bit of anthers/stamen on the right, more of both would be good, but then the bugs would get a little lost. For me, more detail on the bugs would have been good, but 'see above'. Nice capture, and good texture on the petal too.
