Kit lenses can do wonders if you know how to use them well, contrary to all the hype about more expensive gear.
You have gotten a shot from a lower perspective then the insect, and the emptiness of the blue sky around the subject can help to make a good picture. What you may want to consider (in future, such similar opportunities), is to give the blue skies space to accentuate the butterfly on the flower. Cropping a picture here and there just because others may prefer so does not mean that you will get a good picture. Look around, outside of this forum, outside of this little island, if you will. There are examples of wonderful photos, with a similar composition. What works for them? Does it appeal to you? And then you go along those lines.
