Beautiful picture and I don't agree that you failed the DOF its very good. I like that you see only three leafs of the flower wher the butterfly is sitting on. Nice composition and also nice colors. Because the background is blury , DOF becomes very good.
I love this shot of the butterfly. The composition is perfect and the colors are bright and vibrant, very well done.
It's really beautiful! again a perfect exposure and a very nice composition.I like it!
Have a nice weekend
PD: I'm agree with wolfke74,the DOF is perfect.
