Great light, great subject!
I love the expression on the kid's face

But I find the background a little distracting..
I don't know how to rate it though...
Can I just leave my comments without a rate?
If no, then feel free to spank me

Here's my contribution...
Picture taken in April at Butterfly World in Fort Lauderdale, Florida...
I took so many pictures 'm not even finished going through them all...
And as I learn more post editing techniques, I play around a little more..
On this one I cropped it a little, and added some 'netteté' (the English word doesn't come in my mind atm)..
Blurred the background to get a smoother finish...
And ofc I added the border

But I'm not quite satisfied with the focus... The eye is not sharp enough

Still working on this on my new camera

I love the perspective, i hate when people shoot straight down at butterflys, snapping a shot from sideways is the best approach IMO. The composition is great, but it's lacking the "pop". Colors don't seem too rich.. semi de-saturated feeling. Also it's slightly soft. A little shallower DoF would help as well.
This is a great example, i learn by looking at other people's pictures, maybe you do too.
I would post something different.. i went to an exotic car exhibition couple days ago. But i had to sign an agreement in order to get a photography permit. I'm not allow to post those pictures
