It is a very nice portrait probably taken in a parc during summer I guess, the expression of the face is well captured on the picture. The focus is perfect, the texture of the shirt is well rendered.
The photo is classical but colors are pleasant.
I appreciate also the fuzzy in the background, you have a good technique! Shadows are perfects on the face and the shirt.
The only negative critique I can do is about the contrast, I think it should be reduced a bit, it is especially visible on the shirt.
In conclusion it is a good work.
