Fair composition and nice colors. The soft focus detracts from the photo a little. It appears to be from camera motion.
Try using a faster shutter speed
Composition could be improved by moving butterfly to the left. Placing the subject in the center, in effect, divides the picture into two halves. Photography often defies mathematics; two halves seldom makes a good whole.
The out-of-focus background is a plus, drawing more attention to the subject, as is the pleasing contrast.
This is great! I can never get that close to pretty butterflies, they always fly away *sobs*. The colours work well, perfecto. Great job! Keep it up!
