Well, congrats on such a spectacular photo! This is incredible.
The first thing the eye is drawn to is the bee. His wings are focused in on perfectly. There is enough detail that the fuzz on his back is visible. Wonderful job there. The background is also blurred out of focus, only adding to the bee's showcase.
There are only a couple suggestions I have- first, maybe use the rule of thirds. Here you've framed around the bee so he is smack dab in the center. Maybe put him in a corner or on one side. And second, maybe play with the colors or even make it black and white. There's just almost a little too much yellow in the picture.
Once again, fantastic job. I love looking at your photos and seeing how you improve with each one. You should be really proud of this one; it turned out GREAT!!
