Let's start by saying that the colours of the shot are trully striking. The blend of turquise and green make this stand out in a sum of photographs. The magnification is impressive, as is the well blurred background, while the focus is solid on the eyes and front legs. Anyone that has taken one insect macro shot surely knows that it's quite easy to be lost in the narrow depth of field and actually focusing milimeters away, thus losing a good macro shot.

However, there are issues with the shot.

First of all the frame. Very tight at the top, I'd love to have the rest of the insect's body blurred and faded, my attention travels at the top only to have the image end before the subkect does.
Secondly, wide spaces left and right of the theme. It could be placed at wings of the frame, loosely on the rule of the thirds.
Thirdly, the photo shows signs of lens or sensor dust. While this can happen at any photoshoot (especially in nature), it is quite easy to clean in post processing. Those dust spots really distract from the actual photograph and it's a shame actually, as they can be very easily removed.

Overall, the photo promises a lot at first sight, but fails to deliver the whole viewing experience. Little things obviously, and most of the technique is there, nevertheless, once you get the technique out of the way and it has become sort of a "second nature", more attention should be cast on the actual framing of the subject, an issue more complex and difficult than the shooting, but very very important. All I have to suggest to that is practice, practice, practice, you definately are on the right track.
