hpng : firstly, i would like to thanks for your valuable comments again. The EXIF info of this pic are F5.7 at 1/64 with flash light.
I agreed, the whole image will be more balanced if whole leave was included.
In order to get the leaves in foucs, at least F16 should be used i think. In this situation for F16, shutter speed will be as slow as 1/2 to 1 second; may i ask is this settings are possible to take living butterfly ? Would it be practical ?
