Technical issues rejections. Can anyone give some help?

Even though it is a high key photo, it is overexposed. There are no midtones. If you adjust the midtones, more toward the middle of the histogram, artifacts appear in the background. The shadows also are not good. The background should be furtherh away from the subject. Also, the subject should have more details and be propüerly focused. 

Such a minimalist motif should shine through details. I can barely see any details.
