I think you are on the right track. Here is what I would suggest as starting points for corrections. Number 1, loose the blur. The only blur I would use is a lens-zoom blur but this is a fairly advanced trick.
Number 2, two main problems to address. First is lens flare, you don't want it. Make sure you are using the lens hood with your lens. If you don't have one, get one. Second is the loss of detail in the subject's face. Use a flash outdoors, or at least a reflector. In this case both would be best. Get the detail back in the face.
Number 3, your best shot. However, there is too much dead space around the subject. Crop in and get rid of the excess space you don't need.
Great start! Keep shooting to keep improving!
